Leviticus 25:23-25

23“ ‘The land must not be sold permanently, because the land is mine and you reside in my land as foreigners and strangers.

24Throughout the land that you hold as a possession, you must provide for the redemption of the land. 25“ ‘If one of your fellow Israelites becomes poor and sells some of their property, their nearest relative is to come and redeem what they have sold.
