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.

— Leviticus 25:52 —

⁵³as a hireling; he shall be with him from year to year; thou shalt not oppress him with labor before thee.

⁵⁴And if he do not pay his ransom accordingly, he shall go out in the year of his release, he and his children with him.
