Leviticus 25:1-7

The LORD then spoke to Moses at Mount Sinai, saying, “Speak to the sons of Israel and say to them, ‘When you come into the land which I shall give you, then the land shall have a sabbath to the LORD. Six years you shall sow your field, and six years you shall prune your vineyard and gather in its crop, but during the seventh year the land shall have a sabbath rest, a sabbath to the LORD; you shall not sow your field nor prune your vineyard. Your harvest’s aftergrowth you shall not reap, and your grapes of untrimmed vines you shall not gather; the land shall have a sabbatical year. All of you shall have the sabbath products of the land for food; yourself, and your male and female slaves, and your hired man and your foreign resident, those who live as aliens with you. Even your cattle and the animals that are in your land shall have all its crops to eat.
