Leviticus 25:6-9

⁶And the sabbath of the land shall be for food for you, for thee, and for thy bondman, and for thy handmaid, and for thy hired servant, and for him that dwelleth as a sojourner with thee, and for thy cattle,

⁷and for the beasts that are in thy land: all the produce thereof shall be for food.

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.
