Leviticus 25:5-8

⁵That which groweth of its own accord of thy harvest, thou shalt not reap, neither gather the grapes of thy vine undressed: for it is a year of rest to the land.

⁶And the sabbath of the land shall be food for you; for thee, and for thy servant, and for thy maid, and for thy hired servant, and for thy stranger that sojourneth with thee,

⁷And for thy cattle, and for the beast that are in thy land, shall all the increase of it be food.

⁸And thou shalt number seven sabbaths of years to thee, seven times seven years; and the space of the seven sabbaths of years shall be to thee forty and nine years.
