Leviticus 25:2-4

“Tell the people of Israel this: ‘When you enter the land I will give you, let it have a special time of rest, to honor the LORD. You may plant seed in your field for six years, and you may trim your vineyards for six years and bring in their fruits. 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.
