Leviticus 25:8-11

⁸“‘You shall count off seven Sabbaths of years, seven times seven years; and there shall be to you the days of seven Sabbaths of years, even forty-nine years.

⁹Then you shall sound the loud trumpet on the tenth day of the seventh month. On the Day of Atonement you shall sound the trumpet throughout all your land.

¹⁰You shall make the fiftieth year holy, and proclaim liberty throughout the land to all its inhabitants. It shall be a jubilee to you; and each of you shall return to his own property, and each of you shall return to his family.

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.
