Leviticus 18:3; Leviticus 18:26; Leviticus 18:30

3 You shall not do as they do in the land of Egypt, where you lived, and you shall not do as they do in the land of Canaan, to which I am bringing you. You shall not walk in their statutes.

26 But you shall keep my statutes and my rules and do none of these abominations, either the native or the stranger who sojourns among you

30 So keep my charge never to practice any of these abominable customs that were practiced before you, and never to make yourselves unclean by them: I am the LORD your God."
