Leviticus 26:32-33, 43

Yes, I myself will devastate your land, and your enemies who come to occupy it will be appalled at what they see. I will scatter you among the nations and bring out my sword against you. Your land will become desolate, and your cities will lie in ruins.

For the land must be abandoned to enjoy its years of Sabbath rest as it lies deserted. At last the people will pay for their sins, for they have continually rejected my regulations and despised my decrees.
