Leviticus 25:7-9

American Standard Version

⁷ And for thy cattle, and for the beasts that are in thy land, shall all the increase thereof be for food.

⁸ And thou shalt number seven sabbaths of years unto thee, seven times seven years; and there shall be unto thee the days of seven sabbaths of years, even forty and nine years. ⁹ Then shalt thou send abroad the loud trumpet on the tenth day of the seventh month; in the day of atonement shall ye send abroad the trumpet throughout all your land.
