Leviticus 25:7-9

Darby Translation

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

⁸ And 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.

⁹ Then 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.
