Leviticus 18:28-30

28so that the land will not vomit you out should you defile it, as it has vomited out the nation which was there before you.

29For whoever does any of these abominations, those persons who do so shall be cut off from among their people.

30So you are to keep 1your 2commitment to Me not to practice any of the abominable customs which have been practiced before you, so that you do not defile yourselves with them; 3I am the Lord your God.’”
