Leviticus 25:2-5

²Speak to the children of Israel, and you shall say to them, Whenever you° shall have entered into the land, which I give to you, then the land shall rest which I give to you, for its sabbaths to the Lord.

³Six years you shall sow your field, and six years you shall prune your vine, and gather in its fruit.

⁴But in the seventh year shall be a sabbath, it shall be a rest to the land, a sabbath to the Lord: you shall not sow your field, and you shall not prune your vine.

⁵And you shall not gather the spontaneous produce of your field, and you shall not gather fully the grapes of your dedication: it shall be a year of rest to the land.
