Leviticus 25:47-51

⁴⁷If a foreigner or someone living temporarily with you has become wealthy, and if one of your fellow Israelites has become poor and sells himself to that foreigner, or to someone in a foreigner's family,

⁴⁸after your fellow Israelite has been bought, he may be bought back. Someone in his family may redeem him.

⁴⁹It might be the person's uncle, or his uncle's son, who redeems him, or anyone who is his close relative from his family. Or, if he has become prosperous, he may redeem himself.

⁵⁰He must bargain with the man who bought him; they must count the years from the year he sold himself to his purchaser until the year of Jubilee. The price of his redemption must be figured in keeping with the rate paid to a hired servant, for the number of years he might continue to work for the one who bought him.

⁵¹If there are still many years until the year of Jubilee, he must pay back as the price for his redemption an amount of money that is in proportion to the number of those years.
