Leviticus 25:3-5

New Century Version

³ You may plant seed in your field for six years, and you may trim your vineyards for six years and bring in their fruits. ⁴ But during the seventh year, you must let the land rest. This will be a special time to honor the Lord. You must not plant seed in your field or trim your vineyards. ⁵ You must not cut the crops that grow by themselves after harvest, or gather the grapes from your vines that are not trimmed. The land will have a year of rest.
