Leviticus 25:8-11

⁸And thou shalt number seven sabbaths of years to thee, seven times seven years; and the space of the seven sabbaths of years shall be to thee forty and nine years.

⁹Then shalt thou cause the trumpet of the jubilee 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.

¹⁰And ye shall hallow the fiftieth year, and proclaim liberty throughout all the land to all its inhabitants: it shall be a jubilee to you; and ye shall return every man to his possession, and ye shall return every man to his family.

¹¹A jubilee shall that fiftieth year be to you: ye shall not sow, neither reap that which groweth of itself in it, nor gather the grapes in it of thy vine undressed.
