Leviticus 18:26
“Ye shall therefore keep my statutes and my judgments, and shall not commit any of these abominations; neither any of your own nation, nor any stranger that sojourneth among you:”
Defile not ye yourselves in any of these things: for in all these the nations are defiled which I cast out before you:
And the land is defiled: therefore I do visit the iniquity thereof upon it, and the land itself vomiteth out her inhabitants.
Ye shall therefore keep my statutes and my judgments, and shall not commit any of these abominations; neither any of your own nation, nor any stranger that sojourneth among you:
(For all these abominations have the men of the land done, which were before you, and the land is defiled;)
That the land spue not you out also, when ye defile it, as it spued out the nations that were before you.
