Leviticus 18:28

That the land spue not you out also, when ye defile it, as it spued out the nations that were before you.

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

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

and the land doth not vomit you out in your defiling it, as it hath vomited out the nation which `is' before you;

So if you defile the land, it will vomit you out as it spewed out the nations before you.
