Leviticus 25:49

⁴⁷And if a stranger or sojourner with thee wax rich, and thy brother in distress be sold to the stranger or the sojourner that is with thee, or to a proselyte by extraction;

⁴⁸after he is sold to him there shall be redemption for him, one of his brethren shall redeem him.

— Leviticus 25:49 —

⁵⁰then shall he calculate with his purchaser from the year that he sold himself to him until the year of release: and the money of his purchase shall be as that of a hireling, he shall be with him from year to year.

⁵¹And if any have a greater number of years than enough, according to these he shall pay his ransom out of his purchase money.
