Leviticus 25:5-8

⁵That which groweth of itself of thy harvest thou shalt not reap, and the grapes of thy undressed vine thou shalt not gather; it shall be a year of solemn rest for the land.

⁶And the sabbath-produce 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 the settler by thy side that 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.
