Leviticus 25:6-8

American Standard Version

⁶ And 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. 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.
