Leviticus 18:24-30

²⁴Defile not ye yourselves in any of these things; for in all these the nations are defiled which I cast out before you:

²⁵And the land is defiled: therefore I do visit its iniquity upon it, and the land itself vomiteth out her inhabitants.

²⁶Ye 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.

²⁷(For all these abominations have the men of the land done, who were before you, and the land is defiled;)

²⁸That the land may not vomit you out also, when ye defile it, as it vomited out the nations that were before you.

²⁹For whoever shall commit any of these abominations, even the souls that commit them shall be cut off from among their people.

³⁰Therefore shall ye keep my ordinance, that ye commit not any one of these abominable customs, which were committed before you, and that ye defile not yourselves in them; I am the LORD your God.
