TSK · Leviticus 27:17

Then shalt thou cause the trumpet of the jubile to sound on the tenth [day] of the seventh month, in the day of atonement shall ye make the trumpet sound throughout all your land.

A jubile shall that fiftieth year be unto you: ye shall not sow, neither reap that which groweth of itself in it, nor gather [the grapes] in it of thy vine undressed.
