Leviticus 18:28-30

²⁸that the land vomit not you out also, when ye defile it, as it vomited out the nation that was before you.

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

³⁰Therefore shall ye keep My charge, that ye do not any of these abominable customs, which were done before you, and that ye defile not yourselves therein: I am the LORD your God.
