Leviticus 25:2-4

Amplified Bible

² “Speak to the children of Israel and say to them, ‘When you come into the land which I am giving you, then the land shall keep a Sabbath to the Lord. ³ For six years you shall sow your field, and for six years you shall prune your vineyard and gather in its crop. ⁴ But in the seventh year there shall be a Sabbath of rest for the land, a Sabbath to the Lord; you shall not sow [seed in] your field nor prune your vineyard.
