Leviticus 25:23-25

23‘The land shall not be sold permanently, for the land is Mine; you are [only] foreigners and temporary residents with Me.

24So in all the country that you possess, you are to provide for the redemption of the land [in the Year of Jubilee].

25‘If a fellow countryman of yours becomes so poor he has to sell some of his property, then his nearest relative is to come and buy back (redeem) what his relative has sold.
