Leviticus 25:21-25

²¹Then will I send my blessing upon you in the sixth year, and the land shall produce its fruits for three years.

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.
