Leviticus 25:24-29

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.

²⁸But if his hand have not prospered sufficiently, so as that he should restore the money to him, then he that bought the possessions shall have them till the sixth year of the release; and it shall go out in the release, and the owner shall return to his possession.

²⁹And if anyone should sell an inhabited house in a walled city, then there shall be the ransom of it, until the time is fulfilled: its time of ransom shall be a full year.
