Leviticus 25:23-25

²³And the land shall not be sold for a permanence; for the land is mine, because you° are strangers and sojourners before me.

²⁴And in every land of your possession, you° shall allow ransoms for the land.

²⁵And if your brother who is with you be poor, and should have sold part of his possession, and his kinsman who is near to him come, then he shall redeem the possession which his brother has sold.
