Leviticus 18:28-30

28[do none of these things] so that the land will not vomit you out, should you defile it, as it has vomited out the nation which has been before you.

29For whoever commits any of these repulsive acts, those persons who do so shall be cut off from among their people [excluding them from the atonement made for them].

30So keep My command: do not practice any of the repulsive customs which have been practiced before you, so as not to defile yourselves by them; I am the Lord your God.’ ”
