Leviticus 25:22-27

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

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

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

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

²⁶And if one have no near kinsman, and he prosper with his hand, and he find sufficient money, even his ransom;

²⁷then shall he calculate the years of his sale, and he shall give what is due to the man to whom he sold it, and he shall return to his possession.
