Leviticus 25:23-28

“The land shall not be sold in perpetuity, for the land is mine. For you are strangers and sojourners with me. And in all the country you possess, you shall allow a redemption of the land. “If your brother becomes poor and sells part of his property, then his nearest redeemer shall come and redeem what his brother has sold. If a man has no one to redeem it and then himself becomes prosperous and finds sufficient means to redeem it, let him calculate the years since he sold it and pay back the balance to the man to whom he sold it, and then return to his property. But if he does not have sufficient means to recover it, then what he sold shall remain in the hand of the buyer until the year of jubilee. In the jubilee it shall be released, and he shall return to his property.
