1 And the LORD spake unto Moses, saying, 2 Speak unto all the congregation of the children of Israel, and say unto them, Ye shall be holy: for I the LORD your God am holy. 3 Ye shall fear every man his mother, and his father, and keep my sabbaths: I am the LORD your God. 4 Turn ye not unto idols, nor make to yourselves molten gods: I am the LORD your God. 5 And if ye offer a sacrifice of peace offerings unto the LORD, ye shall offer it at your own will. 6 It shall be eaten the same day ye offer it, and on the morrow: and if ought remain until the third day, it shall be burnt in the fire. 7 And if it be eaten at all on the third day, it is abominable; it shall not be accepted. 8 Therefore every one that eateth it shall bear his iniquity, because he hath profaned the hallowed thing of the LORD: and that soul shall be cut off from among his people. 9 And when ye reap the harvest of your land, thou shalt not wholly reap the corners of thy field, neither shalt thou gather the gleanings of thy harvest. 10 And thou shalt not glean thy vineyard, neither shalt thou gather every grape of thy vineyard; thou shalt leave them for the poor and stranger: I am the LORD your God. 11 Ye shall not steal, neither deal falsely, neither lie one to another. 12 And ye shall not swear by my name falsely, neither shalt thou profane the name of thy God: I am the LORD. 13 Thou shalt not defraud thy neighbour, neither rob him: the wages of him that is hired shall not abide with thee all night until the morning. 14 Thou shalt not curse the deaf, nor put a stumblingblock before the blind, but shalt fear thy God: I am the LORD. 15 Ye shall do no unrighteousness in judgment: thou shalt not respect the person of the poor, nor honour the person of the mighty: but in righteousness shalt thou judge thy neighbour. 16 Thou shalt not go up and down as a talebearer among thy people: neither shalt thou stand against the blood of thy neighbour: I am the LORD. 17 Thou shalt not hate thy brother in thine heart: thou shalt in any wise rebuke thy neighbour, and not suffer sin upon him. 18 Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbour as thyself: I am the LORD. 19 Ye shall keep my statutes. Thou shalt not let thy cattle gender with a diverse kind: thou shalt not sow thy field with mingled seed: neither shall a garment mingled of linen and woollen come upon thee. 20 And whosoever lieth carnally with a woman, that is a bondmaid, betrothed to an husband, and not at all redeemed, nor freedom given her; she shall be scourged; they shall not be put to death, because she was not free. 21 And he shall bring his trespass offering unto the LORD, unto the door of the tabernacle of the congregation, even a ram for a trespass offering. 22 And the priest shall make an atonement for him with the ram of the trespass offering before the LORD for his sin which he hath done: and the sin which he hath done shall be forgiven him. 23 And when ye shall come into the land, and shall have planted all manner of trees for food, then ye shall count the fruit thereof as uncircumcised: three years shall it be as uncircumcised unto you: it shall not be eaten of. 24 But in the fourth year all the fruit thereof shall be holy to praise the LORD withal. 25 And in the fifth year shall ye eat of the fruit thereof, that it may yield unto you the increase thereof: I am the LORD your God. 26 Ye shall not eat any thing with the blood: neither shall ye use enchantment, nor observe times. 27 Ye shall not round the corners of your heads, neither shalt thou mar the corners of thy beard. 28 Ye shall not make any cuttings in your flesh for the dead, nor print any marks upon you: I am the LORD. 29 Do not prostitute thy daughter, to cause her to be a whore; lest the land fall to whoredom, and the land become full of wickedness. 30 Ye shall keep my sabbaths, and reverence my sanctuary: I am the LORD. 31 Regard not them that have familiar spirits, neither seek after wizards, to be defiled by them: I am the LORD your God. 32 Thou shalt rise up before the hoary head, and honour the face of the old man, and fear thy God: I am the LORD. 33 And if a stranger sojourn with thee in your land, ye shall not vex him. 34 But the stranger that dwelleth with you shall be unto you as one born among you, and thou shalt love him as thyself; for ye were strangers in the land of Egypt: I am the LORD your God. 35 Ye shall do no unrighteousness in judgment, in meteyard, in weight, or in measure. 36 Just balances, just weights, a just ephah, and a just hin, shall ye have: I am the LORD your God, which brought you out of the land of Egypt. 37 Therefore shall ye observe all my statutes, and all my judgments, and do them: I am the LORD.
[AD 65] 1 Peter on Leviticus 19:2
Wherefore gird up the loins of your mind, be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ; As obedient children, not fashioning yourselves according to the former lusts in your ignorance: But as he which hath called you is holy, so be ye holy in all manner of conversation; Because it is written, Be ye holy; for I am holy. [Leviticus 19:2] And if ye call on the Father, who without respect of persons judgeth according to every man's work, pass the time of your sojourning here in fear: Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers; But with the precious blood of Christ, as of a lamb without blemish and without spot: Who verily was foreordained before the foundation of the world, but was manifest in these last times for you, Who by him do believe in God, that raised him up from the dead, and gave him glory; that your faith and hope might be in God. Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently: Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever. For all flesh is as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away: But the word of the Lord endureth for ever. And this is the word which by the gospel is preached unto you.
[AD 215] Clement of Alexandria on Leviticus 19:9-10
During the harvest, [the law] forbids owners to gather up the bits which fall from the sheaves and similarly advises that in harvesting something should be left behind unreaped. By this it gives excellent teaching to owners in the practice of generous sharing by leaving some of their property for those in need and providing the poor with a chance for food.

[AD 215] Clement of Alexandria on Leviticus 19:9-10
Do you see how the law proclaims simultaneously the justice and goodness of God, who provides food unstintingly for all? Again, in the grape harvest the harvesters are forbidden to go back and cut anything that has been left over or to collect fallen grapes. The same rules are applied to olive gatherers. In fact the principle of tithing crops and flocks was an education in honoring the divine. We are not to be totally absorbed by profit but to share humanely with the neighbor as well.

[AD 397] Ambrose of Milan on Leviticus 19:13
Let no one deny the hireling the wage he is owed, since we too are hirelings of our God, and from him we look forward to the reward of our labor. And if you indeed, whatever type of businessman you are, deny your hireling a monetary payment that is a perishable trifle, you shall be denied the reward of heaven that has been promised. You shall not defraud, as the law says, the hireling of his pay.

[AD 604] Gregory the Dialogist on Leviticus 19:14
To speak evil of the deaf is to disparage one who is absent and does not hear. To put a block before the blind is to do a thing that is proper of itself but which affords an occasion of scandal to one who fails to understand the propriety of it.

[AD 420] Jerome on Leviticus 19:15
“You shall not be partial to the poor,” a precept given lest under pretext of showing pity we should judge an unjust judgment. For each individual is to be judged not by his personal importance but by the merits of his case. His wealth need not stand in the way of the rich man, if he makes a good use of it; and poverty of itself can be no recommendation to the poor if in the midst of squalor and want he fails to stay away from wrongdoing.

[AD 49] James on Leviticus 19:18
My brethren, have not the faith of our Lord Jesus Christ, the Lord of glory, with respect of persons. For if there come unto your assembly a man with a gold ring, in goodly apparel, and there come in also a poor man in vile raiment; And ye have respect to him that weareth the gay clothing, and say unto him, Sit thou here in a good place; and say to the poor, Stand thou there, or sit here under my footstool: Are ye not then partial in yourselves, and are become judges of evil thoughts? Hearken, my beloved brethren, Hath not God chosen the poor of this world rich in faith, and heirs of the kingdom which he hath promised to them that love him? But ye have despised the poor. Do not rich men oppress you, and draw you before the judgment seats? Do not they blaspheme that worthy name by the which ye are called? If ye fulfil the royal law according to the scripture, Thou shalt love thy neighbour as thyself, ye do well: [Leviticus 19:18] But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors. For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all. For he that said, Do not commit adultery, said also, Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the law. So speak ye, and so do, as they that shall be judged by the law of liberty. For he shall have judgment without mercy, that hath showed no mercy; and mercy rejoiceth against judgment.
[AD 50] Galatians on Leviticus 19:18
For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another. For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself. [Leviticus 19:18] But if ye bite and devour one another, take heed that ye be not consumed one of another.
[AD 56] Romans on Leviticus 19:18
Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law. For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself. [Leviticus 19:18] Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.
[AD 60] Mark on Leviticus 19:18
And one of the scribes came, and having heard them reasoning together, and perceiving that he had answered them well, asked him, Which is the first commandment of all? And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord: And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment. And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these. [Leviticus 19:18] And the scribe said unto him, Well, Master, thou hast said the truth: for there is one God; and there is none other but he: And to love him with all the heart, and with all the understanding, and with all the soul, and with all the strength, and to love his neighbour as himself, is more than all whole burnt offerings and sacrifices. And when Jesus saw that he answered discreetly, he said unto him, Thou art not far from the kingdom of God. And no man after that durst ask him any question.
[AD 60] Matthew on Leviticus 19:18
But when the Pharisees had heard that he had put the Sadducees to silence, they were gathered together. Then one of them, which was a lawyer, asked him a question, tempting him, and saying, Master, which is the great commandment in the law? Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. [Leviticus 19:18] On these two commandments hang all the law and the prophets.
[AD 380] Apostolic Constitutions on Leviticus 19:18
Let him use those tenths and first-fruits, which are given according to the command of God, as a man of God; as also let him dispense in a right manner the free-will offerings which are brought in on account of the poor, to the orphans, the widows, the afflicted, and strangers in distress, as having that God for the examiner of his accounts who has committed the disposition to him. Distribute to all those in want with righteousness, and yourselves use the things which belong to the Lord, but do not abuse them; eating of them, but not eating them all up by yourselves: communicate with those that are in want, and thereby show yourselves unblameable before God. For if you shall consume them by yourselves, you will be reproached by God, who says to such unsatiable people, who alone devour all, "You eat up the milk, and clothe yourselves with the wool;" [Ezekiel 34:3] and in another passage, "Must you alone live upon the earth"? [Isaiah 5:8] Upon which account you are commanded in the law, "You shall love your neighbour as yourself." [Leviticus 19:18] Now we say these things, not as if you might not partake of the fruits of your labours; for it is written, "You shall not muzzle the mouth of the ox which treads out the grain;" [Deuteronomy 25:4; 1 Corinthians 9:9] but that you should do it with moderation and righteousness. As, therefore, the ox that labours in the threshing-floor without a muzzle eats indeed, but does not eat all up; so do you who labour in the threshing-floor, that is, in the Church of God, eat of the Church: which was also the case of the Levites, who served in the tabernacle of the testimony, which was in all things a type of the Church.

[AD 430] Augustine of Hippo on Leviticus 19:18
Long before Christ it had been said, “You shall not covet”; long before it had been said, “You shall love your neighbor as yourself,” a phrase which, as the apostle says, expresses the fulfillment of the whole law. And as no one loves himself unless he loves God, the Lord says that the whole Law and the Prophets depend on these two commandments.

[AD 604] Gregory the Dialogist on Leviticus 19:18
A person who does not divide with his needy neighbor what is necessary to him proves that he loves him less than himself. The command is to share two tunics with one’s neighbor: he could not have spoken of a single tunic, since if one is shared no one is clothed. Half a tunic leaves the person who receives it naked, as well as the person who gives it.

[AD 1781] Richard Challoner on Leviticus 19:19
Different seeds: This law tends to recommend simplicity and plain dealing in all things, and to teach the people not to join any false worship or heresy with the worship of the true God.
[AD 391] Pacian of Barcelona on Leviticus 19:23
Fruitbearing trees are works that bring forth virtues. We circumcise trees when we are suspicious of how weak our first efforts are and do not approve of the first fruits of our work. We call the fruit that grows unclean and do not take it as our food. When the first fruits of good works are praised, it is proper that this fruit should not feed the soul of the worker. Otherwise the praise we receive is plucked, and the fruit of our work is eaten out of season. So one who receives praise from a human mouth for a virtue just undertaken eats the fruit of a tree he has planted before its time. Truth said this through the psalmist: “It is vain for you to rise before dawn; rise up after you have sat down.” To rise before dawn is to rejoice in the night of this present life, before the clear light of eternal rewards appears. We should first sit down and then rise up rightly, because whoever does not willingly humble himself now will not be exalted in the glory to come. Exposition of the Old and New Testament, Leviticus

[AD 1781] Richard Challoner on Leviticus 19:23
Firstfruits: Proeputia, literally, their foreskins; it alludes to circumcision, and signifies that for the first three years the trees were to be as uncircumcised, and their fruit unclean: till in the fourth year their increase was sanctified and given to the Lord, that is, to the priests.
