Leviticus 25:4-6

⁴but in the seventh year there shall be a Sabbath of solemn rest for the land, a Sabbath to the LORD. You shall not sow your field or prune your vineyard.

⁵What grows of itself in your harvest you shall not reap, and you shall not gather the grapes of your undressed vine. It shall be a year of solemn rest for the land.

⁶The Sabbath of the land shall be for food for you; for yourself, for your servant, for your maid, for your hired servant, and for your stranger, who lives as a foreigner with you.
