Leviticus 25:22-24

²²And ye shall sow the eighth year, and eat of the fruits, the old store; until the ninth year, until its fruits come in, ye shall eat the old store.

²³And the land shall not be sold in perpetuity; for the land is mine: for ye are strangers and sojourners with me.

²⁴And in all the land of your possession ye shall grant a redemption for the land.
