Leviticus 25:21-23

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

23‘The land, moreover, shall not be sold permanently, because 3the land is Mine; for 4you are only strangers and residents with Me.
