Leviticus 25:5

“Speak to the children of Israel, and tell them, ‘When you come into the land which I give you, then the land shall keep a Sabbath to the LORD.

You shall sow your field six years, and you shall prune your vineyard six years, and gather in its fruits;

but in the seventh year there shall be a Sabbath of solemn rest for the land, a Sabbath to the LORD. You shall not sow your field or prune your vineyard.

The Sabbath of the land shall be for food for you; for yourself, for your servant, for your maid, for your hired servant, and for your stranger, who lives as a foreigner with you.

For your livestock also, and for the animals that are in your land, shall all its increase be for food.

“‘You shall count off seven Sabbaths of years, seven times seven years; and there shall be to you the days of seven Sabbaths of years, even forty-nine years.
