Leviticus 25:28 And if his hand have not found what sufficeth for him to restore it to him, then that which is sold shall remain in the hand of the purchaser, until the year of jubilee; and in the jubilee it shall go out, and he shall return unto his possession. (DBY NAS)
Leviticus 25:30 If it isn't redeemed within the space of a full year, then the house that is in the walled city shall be made sure in perpetuity to him who bought it, throughout his generations. It shall not be released in the Jubilee. (See NAS)
Leviticus 25:50 He shall reckon with him who bought him from the year that he sold himself to him to the Year of Jubilee: and the price of his sale shall be according to the number of years; according to the time of a hired servant shall he be with him. (See NAS)
