Leviticus 25:25-28

“If one of your brothers becomes poor and has to sell any of his land, his nearest relative is to come and buy back what his brother sold. If a man has no one to redeem it but he later prospers and earns enough for its redemption, he is to calculate the value since he sold it and refund the balance to the man to whom he sold it; he can then go back to his own land. If he doesn’t get together enough money to repay him, what he sold remains in the possession of the buyer until the year of Jubilee. In the Jubilee it will be returned and he can go back and live on his land.
