Leviticus 25:8-11

⁸And thou shalt count seven sabbaths of years, seven times seven years; so that the days of the seven sabbaths of years be unto thee forty-nine years.

⁹Then shalt thou cause the loud sound of the trumpet to go forth in the seventh month, on the tenth of the month; on the day of atonement shall ye cause the trumpet to go forth throughout your land.

¹⁰And ye shall hallow the year of the fiftieth year, and proclaim liberty in the land unto all the inhabitants thereof; a year of jubilee shall it be unto you, and ye shall return every man unto his possession, and ye shall return every man unto his family;

¹¹a year of jubilee shall that fiftieth year be unto you: ye shall not sow, neither reap its aftergrowth, nor gather the fruit of its undressed vines.
