Leviticus 25:6-9

⁶And the sabbath of the land shall be for food for you; for thee, and for thy servant and for thy maid, and for thy hired servant and for thy stranger, who sojourn with thee.

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

⁸And 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.

⁹Then 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.
