Leviticus 25:21-23

21then 1I will so order My blessing for you in the sixth year that it will bring forth the crop for three years. 22When you are sowing the eighth year, you can still eat 2old things from the crop, eating the old until the ninth year when its crop comes in.

23‘The land, moreover, shall not be sold permanently, for 3the land is Mine; for 4you are but aliens and sojourners with Me.
