1 And the LORD said unto Moses, Hew thee two tables of stone like unto the first: and I will write upon these tables the words that were in the first tables, which thou brakest. 2 And be ready in the morning, and come up in the morning unto mount Sinai, and present thyself there to me in the top of the mount. 3 And no man shall come up with thee, neither let any man be seen throughout all the mount; neither let the flocks nor herds feed before that mount. 4 And he hewed two tables of stone like unto the first; and Moses rose up early in the morning, and went up unto mount Sinai, as the LORD had commanded him, and took in his hand the two tables of stone. 5 And the LORD descended in the cloud, and stood with him there, and proclaimed the name of the LORD. 6 And the LORD passed by before him, and proclaimed, The LORD, The LORD God, merciful and gracious, longsuffering, and abundant in goodness and truth, 7 Keeping mercy for thousands, forgiving iniquity and transgression and sin, and that will by no means clear the guilty; visiting the iniquity of the fathers upon the children, and upon the children's children, unto the third and to the fourth generation. 8 And Moses made haste, and bowed his head toward the earth, and worshipped. 9 And he said, If now I have found grace in thy sight, O Lord, let my Lord, I pray thee, go among us; for it is a stiffnecked people; and pardon our iniquity and our sin, and take us for thine inheritance. 10 And he said, Behold, I make a covenant: before all thy people I will do marvels, such as have not been done in all the earth, nor in any nation: and all the people among which thou art shall see the work of the LORD: for it is a terrible thing that I will do with thee. 11 Observe thou that which I command thee this day: behold, I drive out before thee the Amorite, and the Canaanite, and the Hittite, and the Perizzite, and the Hivite, and the Jebusite. 12 Take heed to thyself, lest thou make a covenant with the inhabitants of the land whither thou goest, lest it be for a snare in the midst of thee: 13 But ye shall destroy their altars, break their images, and cut down their groves: 14 For thou shalt worship no other god: for the LORD, whose name is Jealous, is a jealous God: 15 Lest thou make a covenant with the inhabitants of the land, and they go a whoring after their gods , and do sacrifice unto their gods, and one call thee, and thou eat of his sacrifice; 16 And thou take of their daughters unto thy sons, and their daughters go a whoring after their gods, and make thy sons go a whoring after their gods. 17 Thou shalt make thee no molten gods. 18 The feast of unleavened bread shalt thou keep. Seven days thou shalt eat unleavened bread, as I commanded thee, in the time of the month Abib: for in the month Abib thou camest out from Egypt. 19 All that openeth the matrix is mine; and every firstling among thy cattle, whether ox or sheep, that is male. 20 But the firstling of an ass thou shalt redeem with a lamb: and if thou redeem him not, then shalt thou break his neck. All the firstborn of thy sons thou shalt redeem. And none shall appear before me empty. 21 Six days thou shalt work, but on the seventh day thou shalt rest: in earing time and in harvest thou shalt rest. 22 And thou shalt observe the feast of weeks, of the firstfruits of wheat harvest, and the feast of ingathering at the year's end. 23 Thrice in the year shall all your men children appear before the Lord GOD, the God of Israel. 24 For I will cast out the nations before thee, and enlarge thy borders: neither shall any man desire thy land, when thou shalt go up to appear before the LORD thy God thrice in the year. 25 Thou shalt not offer the blood of my sacrifice with leaven; neither shall the sacrifice of the feast of the passover be left unto the morning. 26 The first of the firstfruits of thy land thou shalt bring unto the house of the LORD thy God. Thou shalt not seethe a kid in his mother's milk. 27 And the LORD said unto Moses, Write thou these words: for after the tenor of these words I have made a covenant with thee and with Israel. 28 And he was there with the LORD forty days and forty nights; he did neither eat bread, nor drink water. And he wrote upon the tables the words of the covenant, the ten commandments. 29 And it came to pass, when Moses came down from mount Sinai with the two tables of testimony in Moses' hand, when he came down from the mount, that Moses wist not that the skin of his face shone while he talked with him. 30 And when Aaron and all the children of Israel saw Moses, behold, the skin of his face shone; and they were afraid to come nigh him. 31 And Moses called unto them; and Aaron and all the rulers of the congregation returned unto him: and Moses talked with them. 32 And afterward all the children of Israel came nigh: and he gave them in commandment all that the LORD had spoken with him in mount Sinai. 33 And till Moses had done speaking with them, he put a vail on his face. 34 But when Moses went in before the LORD to speak with him, he took the vail off, until he came out. And he came out, and spake unto the children of Israel that which he was commanded. 35 And the children of Israel saw the face of Moses, that the skin of Moses' face shone: and Moses put the vail upon his face again, until he went in to speak with him.
[AD 391] Pacian of Barcelona on Exodus 34:7
What does it mean that the Lord now says through Moses, “You visit the iniquity of fathers on their sons and grandsons”? In these two passages a different sense is found, but the mind of the hearer is taught to inquire subtly along the path of discernment. We inherit original sin from our parents, and unless we are washed by the grace of baptism, we bear even our parents’ sins, because up to that point we are one with them. So God will visit the iniquity of the fathers upon their sons, for, through original sin, the soul of the offspring is stained by the guilt of the parent. But then God does not visit the iniquity of fathers on their sons, because, when we are freed from original guilt through baptism, we no longer have our parents’ guilt but only the guilt for sins we ourselves committed. This passage can also be understood in another way, because when each one imitates the iniquity of his sinful parent, he is rendered guilty through his parent’s fault. But whoever does not imitate the iniquity of his parent is not burdened with his sin. Thus it happens that the sinful son of a sinful father pays the penalty not only for his own sins, which he committed, but also for his father’s sins. For he does not fear to add his own malice to his father’s vices, even though he knows that the Lord is angered by them. It is just that a man who does not fear to imitate the ways of his wicked father before a busy judge is forced in this present life to pay the penalty for the faults of his wicked father. So Scripture says, “The soul of my father is mine; … the soul that sins, that one will die.” For in the flesh sons sometimes perish for their father’s sin. But when the original sin that comes from the parents’ iniquity is forgiven, it is no longer kept in the soul. What does it mean that small children are often snatched away by demons, unless the son’s flesh suffers to punish the father? For the wicked father is struck at in his very self and refuses to sense the force of the blow. Generally he is struck in his sons, so that he burns painfully, and the father’s sorrow is visited on the son’s flesh, insofar as the father’s evil heart is punished by the son’s suffering. But when the sons who are punished for their fathers’ guilt are not little children but already grown, what else should we understand except that they are suffering the punishments of those people whose deeds they imitated? Thus Scripture says rightly, “To the third and fourth generation.” For the sons can see the lives of the parents they imitate up to the third and fourth generation. Punishment extends up to them, for they saw what they would imitate sinfully. Exposition of the Old and New Testament, Exodus

[AD 542] Caesarius of Arles on Exodus 34:12
When the Lord handed over to you the land of the Canaanites, he said, “Take care, therefore, not to make a covenant with these inhabitants of the land that you are to enter; else they will immediately become a snare among you.” Now we believe that by the grace of baptism all sins and offenses have been banished from us. If we afterward make a covenant with those same sins and vices, doubtless this covenant will become a snare for us because of our consent to avarice or dissipation.

[AD 749] John Damascene on Exodus 34:17
“You shall make for yourself no molten gods.” You see that he forbids the making of images because of idolatry and that it is impossible to make an image of the bodiless, invisible and uncircumscribed God. “You saw no form on the day that the Lord spoke.…” And St. Paul, standing in the midst of the Areopagus, says, “Being therefore God’s offspring, we ought not to think that the Deity is like gold, or silver or stone, a representation by the art and imagination of man.”

[AD 420] Jerome on Exodus 34:19
All the heretics have gone astray by not understanding the mystery of his nativity. The statement “He who opens the womb shall be called holy to the Lord” is more applicable to the special nativity of the Savior than to that of all humanity. For Christ alone opened the closed doors of the womb of virginity, which nevertheless remained permanently closed. This is the closed east door, through which only the high priest enters and leaves, and nevertheless it is always closed.

[AD 430] Augustine of Hippo on Exodus 34:28
The forty-day fast of Lent draws its authority from the Old Testament, from the fasts of Moses and Elijah, and from the gospel, because the Lord fasted that many days, showing that the gospel is not at variance with the Law and the Prophets. The Law is personified by Moses, the Prophets by Elijah, between whom the Lord appeared transfigured on the mountain.

[AD 373] Ephrem the Syrian on Exodus 34:29
In Moses he depicted for you a parable:
his cheeks, ashen with age,
became shining and fair,
a symbol of old age
that in Eden again becomes young.

[AD 379] Basil of Caesarea on Exodus 34:29
Every soul is beautiful which is considered by the standard of its own virtues. But most beautiful, true and lovely, which can be contemplated by him alone who has purified his mind, is that of the divine and blessed nature. He who gazes steadfastly at the splendor and graces of it receives some share from it, as if from an immersion, tinging his own face with a sort of brilliant radiance. Whence Moses also was made resplendent in face by receiving some share of beauty when he held converse with God. Therefore he who is conscious of his own beauty utters this act of thanksgiving: “O Lord, in your favor, you gave strength to my beauty.”

[AD 1781] Richard Challoner on Exodus 34:29
Horned: That is, shining, and sending forth rays of light like horns.
[AD 253] Origen of Alexandria on Exodus 34:33
For so long as a man does not attend to the spiritual meaning “a veil lies upon his heart,” in consequence of which veil, in other words his duller understanding, the Scripture itself is said or thought to be veiled. This is the explanation of the veil which is said to have covered the face of Moses when he was speaking to the people, that is, when the law is read in public. But if we turn to the Lord, where also the Word of God is and where the Holy Spirit reveals spiritual knowledge, the veil will be taken away, and we shall then with unveiled face behold in the holy Scriptures the glory of the Lord.

[AD 444] Cyril of Alexandria on Exodus 34:33
The shadows bring forth the truth, even if they are not at all the truth themselves. Because of this, the divinely inspired Moses placed a veil upon his face and spoke thus to the children of Israel, all but shouting by this act that a person might behold the beauty of the utterances made through him, not in outwardly appearing figures but in meditations hidden within us.

[AD 604] Gregory the Dialogist on Exodus 34:34
When Moses comes forth from the sanctuary of God, he veils his shining countenance when in the presence of the people, because he is not going to reveal to the multitude the secrets received in profound enlightenment. Hence God speaking through him enjoined that if anyone dug a pit and neglected to cover it over, then if an ox or an ass fell into it, he should pay the price of the animal. So when a man who has arrived at the deep streams of knowledge does not cover them up before the unlearned hearts of his hearers, he is judged liable to punishment if by his words a soul, whether clean or unclean, takes scandal. Hence it is said to blessed Job: “Who gave the cock understanding?”
