Vayikra (Leviticus): Acharei > Ch 18
Do not commit the sins of the Egyptians and the Canaanites or you will lose the land. Anyone who commits any of these abominations shall be cut off from the midst of their people.
I am the Lord, your G-d. Like the practice of the land of Egypt, in which you dwelled, you shall not do, and like the practice of the land of Canaan, to which I am bringing you, you shall not do, and you shall not follow their statutes. You shall fulfill My ordinances and observe My statutes, to follow them. I am the Lord, your G-d. You shall observe My statutes and My ordinances, which a man shall do and live by them. I am the Lord.
You shall not defile yourselves by any of these things, for the nations, whom I am sending away from before you, have defiled themselves with all these things. And the land became defiled, and I visited its sin upon it, and the land vomited out its inhabitants.
But as for you, you shall observe My statutes and My ordinances, and you shall not do like any of these abominations neither the native, nor the stranger who sojourns among you.
For the people of the land who preceded you, did all of these abominations, and the land became defiled.
And let the land not vomit you out for having defiled it, as it vomited out the nation that preceded you.
For anyone who commits any of these abominations, the persons doing so shall be cut off from the midst of their people. And you shall observe My charge, not to commit any of the abominable practices that were done before you, and you shall not become defiled by them. I am the Lord your G-d.
No man shall come near to any of his close relatives, to uncover [their] nakedness. I am the Lord.
You shall not uncover the nakedness of
your father or your mother
your father's wife; it is your father's nakedness.
your sister, whether your father's daughter or your mother's daughter, whether born to one who may remain in the home or born to one who must be sent outside
your son's daughter or your daughter's daughter, for they are your own nakedness.
the daughter of your father's wife, born to your father she is your sister
your father's sister; she is the close relative of your father
your mother's sister, for she is the close relative of your mother
your father's brother you shall not come near his wife; she is your aunt
your daughter in law; she is your son's wife
your brother's wife: it is your brother's nakedness
To a woman during the uncleanness of her separation, you shall not come near to uncover her nakedness
Sinful forms of marriage
A woman and her daughter; you shall not take [in marriage] her son's daughter or her daughter's daughter, to uncover her nakedness they are close relatives, it is evil counsel.
You shall not take a woman with her sister [in marriage] as rivals, to uncover the nakedness of one upon the other, in her lifetime
Sinful forms of relations
You shall not lie carnally with your neighbor's wife, to become defiled by her
You shall not lie down with a male, as with a woman: this is an abomination.
And with no animal shall you cohabit, to become defiled by it. And a woman shall not stand in front of an animal to cohabit with it; this is depravity.
You shall not give any of your offspring to pass through for Molech. And you shall not profane the Name of your G-d. I am the Lord.
A form of idolatry, named Molech, and this was the manner of its worship, that one would hand over one’s child to the pagan priests, who would make two huge fires. The child was then passed through on foot between these two fires. — [Sanh. 64b]
