'Purchaser' in the Bible

But if he cannot obtain enough to repay him, what he sold will remain in the possession of its purchaser until the Year of Jubilee. It is to be released at the Jubilee, so that he may return to his property.

If it is not redeemed by the end of a full year, then the house in the walled city is permanently transferred to its purchaser throughout his generations. It is not to be released on the Jubilee.

He then with his purchaser shall calculate from the year when he sold himself to him up to the year of jubilee; and the price of his sale shall correspond to the number of years. It is like the days of a hired man that he shall be with him.

If there are still many years [before the Year of Jubilee], in proportion to them he must refund [to the purchaser] part of the price of his sale for his redemption and release.
