Leviticus 25:23-25

American Standard Version

²³ And the land shall not be sold in perpetuity; for the land is mine: for ye are strangers and sojourners with me. ²⁴ And in all the land of your possession ye shall grant a redemption for the land. ²⁵ If thy brother be waxed poor, and sell some of his possession, then shall his kinsman that is next unto him come, and shall redeem that which his brother hath sold.
