18:26 You yourselves must obey my statutes and my regulations and must not do any of these abominations, both the native citizen and the resident foreigner in your midst, 18:27 for the people who were in the land before you have done all these abominations, and the land has become unclean.

Leviticus 18:30

18:30 You must obey my charge to not practice any of the abominable statutes that have been done before you, so that you do not defile yourselves by them. I am the Lord your God.’”
