Leviticus 25:5-8

⁵And thou shalt not gather the spontaneous produce of thy field, and thou shalt not gather fully the grapes of thy dedication: it shall be a year of rest to the land.

⁶And the Sabbaths of the land shall be food for thee, and for thy manservant, and for thy maidservant, and thy hireling, and the stranger that abides with thee.

⁷And for thy cattle, and for the wild beasts that are in thy land, shall every fruit of it be for food.

⁸And thou shalt reckon to thyself seven Sabbaths of years, seven times seven years; and they shall be to thee seven weeks of years, nine and forty years.
