1 Now after the death of Moses the servant of the LORD it came to pass, that the LORD spake unto Joshua the son of Nun, Moses' minister, saying, 2 Moses my servant is dead; now therefore arise, go over this Jordan, thou, and all this people, unto the land which I do give to them, even to the children of Israel. 3 Every place that the sole of your foot shall tread upon, that have I given unto you, as I said unto Moses. 4 From the wilderness and this Lebanon even unto the great river, the river Euphrates, all the land of the Hittites, and unto the great sea toward the going down of the sun, shall be your coast. 5 There shall not any man be able to stand before thee all the days of thy life: as I was with Moses, so I will be with thee: I will not fail thee, nor forsake thee. 6 Be strong and of a good courage: for unto this people shalt thou divide for an inheritance the land, which I sware unto their fathers to give them. 7 Only be thou strong and very courageous, that thou mayest observe to do according to all the law, which Moses my servant commanded thee: turn not from it to the right hand or to the left, that thou mayest prosper whithersoever thou goest. 8 This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success. 9 Have not I commanded thee? Be strong and of a good courage; be not afraid, neither be thou dismayed: for the LORD thy God is with thee whithersoever thou goest. 10 Then Joshua commanded the officers of the people, saying, 11 Pass through the host, and command the people, saying, Prepare you victuals; for within three days ye shall pass over this Jordan, to go in to possess the land, which the LORD your God giveth you to possess it. 12 And to the Reubenites, and to the Gadites, and to half the tribe of Manasseh, spake Joshua, saying, 13 Remember the word which Moses the servant of the LORD commanded you, saying, The LORD your God hath given you rest, and hath given you this land. 14 Your wives, your little ones, and your cattle, shall remain in the land which Moses gave you on this side Jordan; but ye shall pass before your brethren armed, all the mighty men of valour, and help them; 15 Until the LORD have given your brethren rest, as he hath given you, and they also have possessed the land which the LORD your God giveth them: then ye shall return unto the land of your possession, and enjoy it, which Moses the LORD's servant gave you on this side Jordan toward the sunrising. 16 And they answered Joshua, saying, All that thou commandest us we will do, and whithersoever thou sendest us, we will go. 17 According as we hearkened unto Moses in all things, so will we hearken unto thee: only the LORD thy God be with thee, as he was with Moses. 18 Whosoever he be that doth rebel against thy commandment, and will not hearken unto thy words in all that thou commandest him, he shall be put to death: only be strong and of a good courage.
[AD 253] Origen of Alexandria on Joshua 1:1-2
The book does not so much indicate to us the deeds of the son of Nun as it represents for us the mysteries of Jesus my Lord. For he himself is the one who assumes power after the death of Moses; he is the one who leads the army and fights against Amalek. What was foreshadowed there on the mountain by lifted hands was the time when “he attaches [them] to his cross, triumphing over the principalities and powers on it.”2Thus Moses is dead; for the law has ceased, because “the law and the prophets extend only up to John.” Do you want me to bring forth proofs from the Scriptures that the law is called Moses? Hear what he says in the Gospel: “They have Moses and the prophets, let them listen to them.” Here, without any doubt, he calls the law Moses.
Therefore “Moses, the servant of God, is dead”; for the law is dead, and the legal precepts are now invalid.

[AD 325] Lucius Caecilius Firmianus Lactantius on Joshua 1:1-2
For the prophet does not speak this way: “And the Lord said to me,” but to Jesus [Joshua], in order to show that he was not speaking of himself but of Christ to whom God was then speaking. For that Jesus [Joshua] was a figure of Christ. Although he was first called Hoshea, Moses, foreseeing the future, ordered him to be called Joshua (or Jesus), so that, since he was selected leader of the soldiery against Amalek who was attacking the children of Israel, he might overcome the adversary through the figure of his name and lead the people into the land of promise. And for this reason also he succeeded Moses, to show that the new law given through Jesus Christ would succeed the old law which was given through Moses.

[AD 397] Ambrose of Milan on Joshua 1:1-2
Joshua the son of Nun became so great, because his union with Moses was the means not only of instructing him in a knowledge of the law but also of sanctifying him to receive grace. When in his tabernacle the majesty of the Lord was seen to shine forth in its divine Presence, Joshua alone was in the tabernacle. When Moses spoke with God, Joshua too was covered by the sacred cloud. The priests and people stood below, and Joshua and Moses went up the mount to receive the law. All the people were within the camp; Joshua was without the camp in the tabernacle of witness. When the pillar of a cloud came down and God spoke with Moses, Joshua stood as a trusty servant beside him. He, a young man, did not go out of the tabernacle, though the old men who stood far off trembled at these divine wonders.

[AD 407] John Chrysostom on Joshua 1:1-2
The name of Jesus [Joshua] was a type. For this reason then, and because of the very name, the creation reverenced him. What then! Was no other person called Jesus [Joshua]? But this man was on this account so called as a type; for he used to be called Hoshea. Therefore the name was changed: for it was a prediction and a prophecy. He brought in the people into the promised land, as Jesus into heaven; not the law; since neither did Moses [enter the promised land] but remained outside. The law has not power to bring in, but grace.

[AD 420] Jerome on Joshua 1:1
Having finally finished with the Pentateuch of Moses, as though freed for a great advantage, we set (our) hand to Jesus son of Nave, who the Hebrews call Joshua ben Nun, that is, Joshua son of Nun, and to the book of Judges, which they call Sopthim, to Ruth also and Esther, which they extol by the same names. And I admonish the reader, that he, being careful with Scripture, might preserve the forest of Hebrew names and (their) separations divided into parts, so that our work and his effort might not be wasted. And that in the first place, which I often testify, let him know me not to coin the new in rebuke of the old, as though my friends are accused, but rather to offer, for my part, to men of my language, those things of ours which still delight, like the copies of the Hexapla for the Greeks, which require great expense and work, so they might have our edition, and anywhere the readings of the ancient scrolls are doubtful, comparing this this to them, they might find what they seek, especially when among the Latins there are as many versions as there are books, and everyone has, according to his own judgment, either added or subtracted whatever seemed right to him, and he indeed may not have been able to be certain what differed. From which may scorpion cease to rise against me with bow-like wound, and poisoned tongue desist from slandering a holy work, either accepting, if it has pleased, or condemning, if it has displeased, and remember these verses: "Your mouth has abounded in malice, and your tongue constructed deceits; sitting, you have spoken against your brother, and against the son of your mother imposed a scandal. These things you have done and I was quiet; you wrongly thought that I might be like you: I will accuse you and stand before your face" [Psalm 49.19-21]. For what advantage is it to the listener for us to sweat at work and to work at criticizing others, for Jews to lament that the opportunity has been taken away from them for falsely accusing and insulting Christians, and for men of the Church to despise, indeed to tear apart, that from which enemies are tortured. If only what is old in the interpretation pleases them, which things are also not displeasing to me, and they think of receiving nothing further, why are they reading or not reading those things which are either added or cut out by the asterisks and obeli? For what reason have the churches accepted the translation of Daniel by Theodotion? Why are Origen and Eusebius Pamphilou admired for having treated entire editions similarly? Or what foolishness was it, after they had spoken true things, to set forth things which are false? And from where in the New Testament are they able to prove the received testimonies, which are not supported in the books of the Old (Testament)? Thus, we say, I may be seen to be not altogether quiet to accusers.
Otherwise, after the falling asleep of Paula, whose life is an example of virtue, and these books, which I was not able to deny to Eustochium the virgin of Christ, we have decided "while spirit yet rules these limbs" to incline to the explanation of the Prophets, and to resume, in a kind of return home, a work long unfinished, especially when the admirable and holy man Pammachius demands the same in letters, and we, hurrying on to the homeland, need to pass by the deadly songs of the sirens with deaf ear.
[AD 1781] Richard Challoner on Joshua 1:1
This Book is called JOSUE, because it contains the history of what passed under him, and according to the common opinion was written by him. The Greeks call him Jesus: for Josue and Jesus in the Hebrew, are the same name, and have the same signification, viz., A SAVIOUR. And it was not without a mystery that he who was to bring the people into the land of promise should have his name changed from OSEE (for so he was called before, Num. 13.17,) to JOSUE or JESUS, to give us to understand, that Moses by his law could only bring the people within sight of the promised inheritance, but that our Saviour JESUS was to bring us into it.
[AD 253] Origen of Alexandria on Joshua 1:3-4
But let us consider what is promised to us in these words.There are certain diabolical races of powerful adversaries against whom we wage a battle and against whom we struggle in this life. However many of these races we set under our feet, however many we conquer in battle, we shall seize their territories, their provinces and their realms, as Jesus our Lord apportions them to us. For they were once angels; they were glorified in the kingdom of God. Or do we not read that Isaiah says of one of them, “How did Lucifer fall, the one who rose in the morning?” That Lucifer, without a doubt, had a throne in the heavens until he became a fugitive angel. If I should conquer him and set him under my feet, if I should deserve that the Lord Jesus “crush Satan under my feet,” I shall be ready as a consequence to receive the place of Lucifer in heaven.
Thus we understand the promise to us from our Lord Jesus that “every place we set the soles of our feet” will be ours. But let us not imagine that we may be able to enter into this inheritance yawning and drowsy, through ease and negligence. The wrath of his own race possesses the angel [Lucifer]. Unless you vanquish this [wrath] in yourself and cut off all violent impulses of anger and rage, you will not be able to claim as an inheritance the place that angel once had. For you will not expel him from the land of promise by your slothfulness. In like manner, some angels incite pride, jealousy, greed and lust and instigate these evil things. Unless you gain the mastery over their vices in yourself and exterminate them from your land—which now through the grace of baptism has been sanctified—you will not receive the fullness of the promised inheritance.

[AD 253] Origen of Alexandria on Joshua 1:3-4
What are the places we ascend with the soles of our feet? The letter of the law is placed on the ground and lies down below. On no occasion, then, does the one who follows the letter of the law ascend. But if you are able to rise from the letter to the spirit and also ascend from history to a higher understanding, then truly you have ascended the lofty and high place that you will receive from God as your inheritance. For if in these things that are written you perceive types and observe figures of heavenly things, and with reflection and intuitive feeling “you seek those things that are above, where Christ is sitting at the right hand of God,” then you will receive this place as your inheritance. For our Lord and Savior says, “Where I am, there also will be my servant.”19If therefore you have arrived all the way to Christ, who sits at the right hand of God, by your faith, life, purity and virtue, and by those “soles of your feet” that Jesus washed, you have approached that place. God will give it to you. Then not only “will you be made heirs of God” but also “co-heirs with Christ.”

[AD 390] Gregory of Nazianzus on Joshua 1:3-4
What is the special excellence of Joshua? His generalship, and the distribution of the inheritance, and the taking possession of the Holy Land.

[AD 69] Hebrews on Joshua 1:5
Let brotherly love continue. Be not forgetful to entertain strangers: for thereby some have entertained angels unawares. Remember them that are in bonds, as bound with them; and them which suffer adversity, as being yourselves also in the body. Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge. Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee. [Joshua 1:5] So that we may boldly say, The Lord is my helper, and I will not fear what man shall do unto me.
[AD 215] Clement of Alexandria on Joshua 1:5
We must join in disciplining ourselves to beware of all that is subject to the passions. We must, like true philosophers, escape from any foods that arouse sexual desire, from a dissolute relaxation in bed, from luxury and all the passions that make for luxury. We realize that others find this a grievous struggle. It is no longer so for us, since self-discipline is God’s greatest gift. “He has said, ‘I will never forsake you or abandon you,’ ” who has judged you worthy by a decision that is wholly genuine. In this way, as we carefully strive to go to him, the Lord’s “easy yoke” will receive us.

[AD 407] John Chrysostom on Joshua 1:5
Nevertheless, I say, fear not. Paul comforts you saying, “God is faithful, who will not suffer you to be tempted above that which you are able, but will with the temptation also provide the way of escape, that you may be able to bear it.” He indeed himself has said, “I will never leave you or forsake you.” For had he resolved to punish us in deed and in actual endurance, he would not have given us over to terror during so many days. For when he would not punish, he frightens; since if he were intending to punish, fear would be superfluous, and threatening superfluous. But now, we have sustained a life more grievous than countless deaths; fearing and trembling during so many days, and being suspicious of our very shadows; and paying the punishment of Cain;29 and in the midst of our sleep, starting up, through constant agony of mind. So that if we have kindled God’s wrath, we have appeased him in the endurance of such a punishment. For if we have not paid the satisfaction due to our sins, yet it has been enough to satisfy the mercy of God.

[AD 430] Augustine of Hippo on Joshua 1:5
Pay attention to what comes next: “Without love, a measure of money is sufficient for present needs,” because he himself said, “ ‘I will not forsake you, I will not desert you.’ You were afraid of I don’t know what evils, for that reason you were saving up money; count me as your guarantor.” That’s what God says to you. It isn’t a man, not your equal or you yourself, but God who says to you, “I will not forsake you, I will not desert you.” If a man made such a promise, you would trust him; God makes it, and you hesitate? He made the promise, put it in writing, made out the bond; you needn’t worry at all. Read what you’ve got in your hand, you’re holding God’s bond; as your debtor you hold the one whom you have asked to cancel your debts.

[AD 585] Cassiodorus on Joshua 1:5
The fifth kindness follows, which is bestowed with true certainty on every really staunch Catholic. He means: “Even if I were to walk among heretics and schismatics” (they are rightly called the shadow of death since they have the form of death as they lead us to hell) “I will not fear their foul enticements, for you defend me with the protection of your presence.” In the prophet’s words: I will not leave you or forsake you; for in this world the church walks among the wicked, until he who separates the good from the evil shall come on judgment day.

[AD 253] Origen of Alexandria on Joshua 1:6-9
I fear, however, lest by too much negligence and dullness of heart the divine volumes be not only veiled to us but also sealed, so that “if a book should be put into the hands of a man who cannot read, he would say, ‘I cannot read’; if it should be put into the hands of a man who can read, he would say, ‘It is sealed.’ ” Whence it is shown that we must not only employ zeal to learn the sacred literature, but we must also pray to the Lord and entreat “day and night” that the lamb “of the tribe of Judah” may come and himself taking “the sealed book” may deign to open it.

[AD 348] Pachomius the Great on Joshua 1:6-9
Still, toss all pride far from your side, and be valiant. Look: when Joshua [son] of Nun was valiant, God delivered his enemies into his hands. If you are fainthearted, you become a stranger to the law of God. Faintheartedness fills you with pretexts for laziness, mistrust and negligence, until you are destroyed.

[AD 380] Apostolic Constitutions on Joshua 1:6-9
You should not be like a wanderer, rambling about the streets, without just cause, to spy out those who live wickedly. But by minding your own trade and employment, endeavor to do what is acceptable to God. And keeping in mind the oracles of Christ, meditate in the same continually. For so the Scripture says to you: “You shall meditate in his law day and night; when you walk in the field, and when you sit in your house, and when you lie down, and when you rise up, that you may have understanding in all things.” No, although you are rich and so do not want a trade for your maintenance, don’t be one that wonders and walks around at random; but either go to some that are believers, and of the same religion, and confer and discourse with them about the lively oracles of God. Or if you stay at home, read the books of the Law, of the Kings, with the Prophets; sing the hymns of David; and peruse diligently the gospel, which is the completion of the other.

[AD 390] Gregory of Nazianzus on Joshua 1:6-9
What aspects of theology should be investigated, and to what limit? Only aspects within our grasp, and only to the limit of the experience and capacity of our audience. Just as excess of sound or food injures the hearing or general health, or, if you prefer, as loads that are too heavy injure those who carry them, or as excessive rain harms the soil, we too must guard against the danger that the toughness, so to speak, of our discourses may so oppress and overtax our hearers as actually to impair the powers they had before.Yet I am not maintaining that we ought not to be mindful of God at all times. My adversaries, ever ready and quick to attack, need not pounce on me again. It is more important that we should remember God than that we should breathe: indeed, if one may say so, we should do nothing else besides. I am one of those who approve the precept that commands us to “meditate day and night,” to tell of the Lord “evening, and morning, and at noon,” and to “bless the Lord at all times,” or in the words of Moses, “when we lie down, when we rise up, when we walk by the way,” or when we do anything else whatever, and by this mindfulness be molded to purity. So it is not continual remembrance of God I seek to discourage, but continual discussion of theology. I am not opposed either to theology, as if it were a breach of piety, but only to its untimely practice, nor to instruction in theology, except when this goes to excess. Fullness and surfeit even of honey, for all its goodness, produces vomiting; and “to everything there is a season,” as Solomon said I think, and “what’s well is not well if the hour be ill.” A flower is completely out of season in winter, a man’s clothing is out of place on a woman, a woman’s on a man. Immoderate laughter is unseemly during mourning, as are tears at a drinking party. Are we then to neglect “the due season” only in the discussion of theology, where observing the proper time is of such supreme importance?

[AD 542] Caesarius of Arles on Joshua 1:10-11
At the death of Moses, Joshua received the rule; and when the law ended, our true Lord Jesus obtained the rule of the whole world. Therefore, Joshua who typified the Lord said to the people when he came to the Jordan: “Prepare your provisions until the third day.” The third day, dearly beloved, we recognize as the mystery of the Trinity. What food should we prepare so that we may come to the third day? It seems to me that this food should be understood as faith; for Christians it is by faith that they believe in the Trinity and arrive at the sacrament of baptism. Therefore, what Joshua then told his people, the true Joshua or Jesus now tells the Christian people through his ministers. Indeed, what else does this mean: “Prepare your provisions until the third day,” except to receive the mystery of the Trinity? After this the Jordan was crossed just as if the mystery of baptism were completed, and the people of Israel entered the promised land. It is true, brothers; unless a person crosses through the sacrament of baptism, he will not see the land of true promise, that is, eternal beatitude.

[AD 542] Caesarius of Arles on Joshua 1:10-11
For this reason Joshua said to the people, “Prepare your provisions for the journey.” Today, if you willingly listen, Christ our Lord says to you, “If you will follow me, prepare food for the journey.” This food is good works which accompany us like faithful food for the journey to future bliss. Therefore, consider, brothers, that if each one does not prepare food for himself, he cannot follow Joshua when he enters the land of promise.

[AD 253] Origen of Alexandria on Joshua 1:12-15
Let us look closely at what sign those two and a half tribes hold who receive the land of inheritance through Moses, and what sign the remainder of the nine and a half tribes hold who receive the promise of the holy land through Jesus [Joshua].First of all, I think it is impossible for it to have happened accidentally that those who receive a portion through Moses were all firstborn. For Reuben was the firstborn of Leah; Gad, the firstborn of Zilpah;4 and Manasseh, the firstborn of Asenath the Egyptian whom Joseph married, the daughter of Potiphar the priest of Heliopolis. For myself, I can never be persuaded that it was by chance that the firstborn were the only ones whose inheritance was determined through Moses. Rather, I believe that in these things the design of two groups of people was already foreshadowed at that time: One would seem to be the firstborn according to the order of nature; the other, the people who would receive the blessing of their inheritance through faith and grace.

[AD 253] Origen of Alexandria on Joshua 1:12-15
Rest is not given first to those who through Moses receive the inheritance—that is, those who pleased God through the law—unless they assist their brothers in the battles. Only women and infants receive rest through Moses. The others do not rest but go out to the aid of their brothers.…Thus those who are strong men, their loins armed and girded with truth, go forth to our aid and fight with us. But “infants and women” do not go out to our battle. This is not an astonishing thing, for an infant is said to be one who does not speak. How is a person able to assist me who has spoken nothing, the one of whom I discover nothing that I may read, the one who does not instruct me by a word? But the apostle says that a woman is a “weak vessel.” Suitably, therefore, a weak vessel does not come to the conflict lest it be broken in pieces and destroyed. For concerning our Lord Jesus, it is also said in the Gospels that “he did not break a bruised reed.”
