Leviticus 25:18-23

“Therefore you shall do my statutes and keep my rules and perform them, and then you will dwell in the land securely. The land will yield its fruit, and you will eat your fill and dwell in it securely. And if you say, ‘What shall we eat in the seventh year, if we may not sow or gather in our crop?’ I will command my blessing on you in the sixth year, so that it will produce a crop sufficient for three years. When you sow in the eighth year, you will be eating some of the old crop; you shall eat the old until the ninth year, when its crop arrives. “The land shall not be sold in perpetuity, for the land is mine. For you are strangers and sojourners with me.
