Leviticus 25:21-25

²¹I will bless you in the sixth year, so that the land will produce a crop that will be enough for three years.

²²As you sow in the eighth year, you will still be eating from that harvest, which will last until your harvest in the ninth year.

²³Land must not be permanently sold, because it really belongs to me. To me you are only foreigners and travelers passing through.

²⁴So whatever land you buy to own, you must make arrangements so it can be returned to its original owner.

²⁵If one of your people becomes poor and sells you some of their land, their close family can come and buy back what they have sold.
