Leviticus 25:7-10

⁷And for your cattle, and for the wild beats that are in your land, shall every fruit of it be for food.

⁸And you shall reckon to yourself seven sabbaths of years, seven times seven years; and they shall be to you seven weeks of years, nine and forty years.

⁹In the seventh month, on the tenth day of the month, you° shall make a proclamation with the sound of a trumpet in all your land; on the day of atonement you° shall make a proclamation with a trumpet in all your land.

¹⁰And you° shall sanctify the year, the fifties year, and you° shall proclaim a release upon the land to all that inhabit it; it shall be given a year of release, a jubilee for you; and each one shall depart to his possession, and you° shall go each to his family.
