Leviticus 25:2-5

²'Speak unto the sons of Israel, and thou hast said unto them, When ye come in unto the land which I am giving to you, then hath the land kept a sabbath to Jehovah.

³'Six years thou dost sow thy field, and six years thou dost prune thy vineyard, and hast gathered its increase,

⁴and in the seventh year a sabbath of rest is to the land, a sabbath to Jehovah; thy field thou dost not sow, and thy vineyard thou dost not prune;

⁵the spontaneous growth of thy harvest thou dost not reap, and the grapes of thy separated thing thou dost not gather, a year of rest it is to the land.
