Leviticus 25:24-28

So for every piece of your property, you are to provide for the redemption of the land.

‘If a fellow countryman of yours becomes so poor that he sells part of his property, then his closest redeemer is to come and buy back what his relative has sold.

Or in case someone has no redeemer, but recovers to find sufficient means for its redemption,

then he shall calculate the years since its sale and refund the balance to the man to whom he sold it, and so return to his property.

But if he has not found sufficient means to get it back for himself, then what he has sold shall remain in the hands of its purchaser until the year of jubilee; but at the jubilee it shall revert, so that he may return to his property.
