Leviticus 25:22-24

²²Then, after you plant seed during the eighth/next year and wait for the crops to grow, you will eat the food grown in the sixth year, and continue to eat it until more food is harvested in the ninth year!

²³You must not sell any of your land to belong to someone else permanently, because the land is not yours; it is really mine, and you are only living on it temporarily and ◄farming/taking care of► it for me.

²⁴Throughout the land that you will possess, you must remember that if someone sells some of his land to you, he is permitted to buy it back from you if he wants to.
