Leviticus 25:13

11That fiftieth year shall be a jubilee to you. In it you shall not sow, neither reap that which grows of itself, nor gather from the undressed vines.

12For it is a jubilee; it shall be holy to you. You shall eat of its increase out of the field.

13“‘In this Year of Jubilee each of you shall return to his property.

14“‘If you sell anything to your neighbor, or buy from your neighbor, you shall not wrong one another.

15According to the number of years after the Jubilee you shall buy from your neighbor. According to the number of years of the crops he shall sell to you.
