1 And the LORD spake unto Moses, saying, 2 Speak unto the children of Israel, and say unto them, I am the LORD your God. 3 After the doings of the land of Egypt, wherein ye dwelt, shall ye not do: and after the doings of the land of Canaan, whither I bring you, shall ye not do: neither shall ye walk in their ordinances. 4 Ye shall do my judgments, and keep mine ordinances, to walk therein: I am the LORD your God. 5 Ye shall therefore keep my statutes, and my judgments: which if a man do, he shall live in them: I am the LORD. 6 None of you shall approach to any that is near of kin to him, to uncover their nakedness: I am the LORD. 7 The nakedness of thy father, or the nakedness of thy mother, shalt thou not uncover: she is thy mother; thou shalt not uncover her nakedness. 8 The nakedness of thy father's wife shalt thou not uncover: it is thy father's nakedness. 9 The nakedness of thy sister, the daughter of thy father, or daughter of thy mother, whether she be born at home, or born abroad, even their nakedness thou shalt not uncover. 10 The nakedness of thy son's daughter, or of thy daughter's daughter, even their nakedness thou shalt not uncover: for theirs is thine own nakedness. 11 The nakedness of thy father's wife's daughter, begotten of thy father, she is thy sister, thou shalt not uncover her nakedness. 12 Thou shalt not uncover the nakedness of thy father's sister: she is thy father's near kinswoman. 13 Thou shalt not uncover the nakedness of thy mother's sister: for she is thy mother's near kinswoman. 14 Thou shalt not uncover the nakedness of thy father's brother, thou shalt not approach to his wife: she is thine aunt. 15 Thou shalt not uncover the nakedness of thy daughter in law: she is thy son's wife; thou shalt not uncover her nakedness. 16 Thou shalt not uncover the nakedness of thy brother's wife: it is thy brother's nakedness. 17 Thou shalt not uncover the nakedness of a woman and her daughter, neither shalt thou take her son's daughter, or her daughter's daughter, to uncover her nakedness; for they are her near kinswomen: it is wickedness. 18 Neither shalt thou take a wife to her sister, to vex her, to uncover her nakedness, beside the other in her life time. 19 Also thou shalt not approach unto a woman to uncover her nakedness, as long as she is put apart for her uncleanness. 20 Moreover thou shalt not lie carnally with thy neighbour's wife, to defile thyself with her. 21 And thou shalt not let any of thy seed pass through the fire to Molech, neither shalt thou profane the name of thy God: I am the LORD. 22 Thou shalt not lie with mankind, as with womankind: it is abomination. 23 Neither shalt thou lie with any beast to defile thyself therewith: neither shall any woman stand before a beast to lie down thereto: it is confusion. 24 Defile not ye yourselves in any of these things: for in all these the nations are defiled which I cast out before you: 25 And the land is defiled: therefore I do visit the iniquity thereof upon it, and the land itself vomiteth out her inhabitants. 26 Ye shall therefore keep my statutes and my judgments, and shall not commit any of these abominations; neither any of your own nation, nor any stranger that sojourneth among you: 27 (For all these abominations have the men of the land done, which were before you, and the land is defiled;) 28 That the land spue not you out also, when ye defile it, as it spued out the nations that were before you. 29 For whosoever shall commit any of these abominations, even the souls that commit them shall be cut off from among their people. 30 Therefore shall ye keep mine ordinance, that ye commit not any one of these abominable customs, which were committed before you, and that ye defile not yourselves therein: I am the LORD your God.
[AD 50] Galatians on Leviticus 18:5
For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them. But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith. And the law is not of faith: but, The man that doeth them shall live in them. [Leviticus 18:5] Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree: That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith.
[AD 56] Romans on Leviticus 18:5
For Moses describeth the righteousness which is of the law, That the man which doeth those things shall live by them. [Leviticus 18:5] But the righteousness which is of faith speaketh on this wise, Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down from above:) Or, Who shall descend into the deep? (that is, to bring up Christ again from the dead.) But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. For the scripture saith, Whosoever believeth on him shall not be ashamed. For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him. For whosoever shall call upon the name of the Lord shall be saved.
[AD 420] Jerome on Leviticus 18:5
“The man who carries out the law will find life through it.” Scripture did not say he will find life through it, in the sense that through the law he will live in heaven, but he will find life through it to the extent that what he merits, he reaps in the present world.

[AD 430] Augustine of Hippo on Leviticus 18:5
The righteousness of the law, of which it is said that if a man does it he shall live in it, is set forth to this end: that every man may recognize his own infirmity. It is not in his own strength or through the letter of the law (which cannot be) but only by receiving through faith the favor of the Justifier that he may attain and do and live in righteousness.

[AD 435] John Cassian on Leviticus 18:5
For the law promises those who practice it not the rewards of the heavenly kingdom but the consolations of this life when it says, “The one who does these things shall live in them.” But the Lord says to his disciples, “Blessed are the poor in spirit, for theirs is the kingdom of heaven.”

[AD 1781] Richard Challoner on Leviticus 18:23
Because it is a heinous crime: In Hebrew, this word heinous crime is expressed by the word confusion, signifying the shamefulness and baseness of this abominable sin.
