Leviticus 18:22-30; Leviticus 20:8-22
Do not lie with a male as one lies with a woman; it is an abhorrence.
Do not have carnal relations with any beast and defile yourself thereby; and let no woman lend herself to a beast to mate with it; it is perversion.
Do not defile yourselves in any of those ways, for it is by such that the nations that I am casting out before you defiled themselves. Thus the land became defiled; and I called it to account for its iniquity, and the land spewed out its inhabitants. But you must keep My laws and My rules, and you must not do any of those abhorrent things, neither the citizen nor the stranger who resides among you; for all those abhorrent things were done by the people who were in the land before you, and the land became defiled. So let not the land spew you out for defiling it, as it spewed out the nation that came before you. All who do any of those abhorrent things--such persons shall be cut off from their people. You shall keep My charge not to engage in any of the abhorrent practices that were carried on before you, and you shall not defile yourselves through them: I the Lord am your God.
You shall faithfully observe My laws: I the Lord make you holy.
If anyone insults his father or his mother, he shall be put to death; he has insulted his father and his mother--his bloodguilt is upon him.
If a man commits adultery with a married woman, committing adultery with another man's wife, the adulterer and the adulteress shall be put to death. If a man lies with his father's wife, it is the nakedness of his father that he has uncovered; the two shall be put to death--their bloodguilt is upon them. If a man lies with his daughter-in-law, both of them shall be put to death; they have committed incest--their bloodguilt is upon them. If a man lies with a male as one lies with a woman, the two of them have done an abhorrent thing; they shall be put to death--their bloodguilt is upon them. If a man marries a woman and her mother, it is depravity; both he and they shall be put to the fire, that there be no depravity among you. If a man has carnal relations with a beast, he shall be put to death; and you shall kill the beast. If a woman approaches any beast to mate with it, you shall kill the woman and the beast; they shall be put to death--their bloodguilt is upon them.
If a man marries his sister, the daughter of either his father or his mother, so that he sees her nakedness and she sees his nakedness, it is a disgrace; they shall be excommunicated in the sight of their kinsfolk. He has uncovered the nakedness of his sister, he shall bear his guilt. If a man lies with a woman in her infirmity and uncovers her nakedness, he has laid bare her flow and she has exposed her blood flow; both of them shall be cut off from among their people. You shall not uncover the nakedness of your mother's sister or of your father's sister, for that is laying bare one's own flesh; they shall bear their guilt. If a man lies with his uncle's wife, it is his uncle's nakedness that he has uncovered. They shall bear their guilt: they shall die childless. If a man marries the wife of his brother, it is indecency. It is the nakedness of his brother that he has uncovered; they shall remain childless.
You shall faithfully observe all My laws and all My regulations, lest the land to which I bring you to settle in spew you out.
