Leviticus 25:27-28

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.
