Leviticus 18:24-29

²⁴Do not make yourself unclean in any of these ways; for so have those nations whom I am driving out from before you made themselves unclean:

²⁵And the land itself has become unclean; so that I have sent on it the reward of its wrongdoing, and the land itself puts out those who are living in it.

²⁶So then keep my rules and my decisions, and do not do any of these disgusting things, those of you who are Israelites by birth, or any others who are living with you:

²⁷(For all these disgusting things were done by the men of this country who were there before you, and the land has been made unclean by them;)

²⁸So that the land may not put you out from it, when you make it unclean, as it put out the nations which were there before you.

²⁹For all those who do any of these disgusting things will be cut off from among their people.
