Leviticus 25:2-7

2Speak to the children of Israel, and say to them, When ye come into the land which I give you, then shall the land keep a sabbath to the LORD.1 3Six years thou shalt sow thy field, and six years thou shalt prune thy vineyard, and gather in its fruit; 4But in the seventh year shall be a sabbath of rest to the land, a sabbath for the LORD: thou shalt neither sow thy field, nor prune thy vineyard. 5That which groweth of its own accord of thy harvest thou shalt not reap, neither gather the grapes of thy untrimmed vine: for it is a year of rest to the land.2 6And the sabbath of the land shall be food for you; for thee, and for thy male servant, and for thy female servant, 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.
