Leviticus 25:4-6

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.

⁶And the sabbaths of the land shall be food for you, and for your man-servant, and for your maidservant, and your hireling, and the stranger that abides with you.
