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 from before you.

²⁵And the land was defiled, therefore I did visit the iniquity thereof upon it, and the land vomited out her inhabitants.

²⁶Ye therefore shall keep My statutes and Mine ordinances, and shall not do any of these abominations; neither the home-born, nor the stranger that sojourneth among you —

²⁷for all these abominations have the men of the land done, that were before you, and the land is defiled —

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.
