Leviticus 25:8-11

⁸And let seven Sabbaths of years be numbered to you, seven times seven years; even the days of seven Sabbaths of years, that is forty-nine years;

⁹Then let the loud horn be sounded far and wide on the tenth day of the seventh month; on the day of taking away sin let the horn be sounded through all your land.

¹⁰And let this fiftieth year be kept holy, and say publicly that everyone in the land is free from debt: it is the Jubilee, and every man may go back to his heritage and to his family.

¹¹Let this fiftieth year be the Jubilee: no seed may be planted, and that which comes to growth of itself may not be cut, and the grapes may not be taken from the uncared-for vines.
