Leviticus 25:23-25

23‘The land, moreover, shall not be sold permanently, for 1the land is Mine; for 2you are but aliens and sojourners with Me. 24Thus for every 3piece of your property, you are to provide for the redemption of the land.

25‘4If a 5fellow countryman of yours becomes so poor he has to sell part of his property, then his nearest kinsman is to come and buy back what his 6relative has sold.
