Leviticus 25:3-9

³You shall sow your field six years, and you shall prune your vineyard six years, and gather in its fruits;

⁴but 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.

⁵What grows of itself in your harvest you shall not reap, and you shall not gather the grapes of your undressed vine. It shall be a year of solemn rest for the land.

⁶The 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.

⁷For your livestock also, and for the animals that are in your land, shall all its increase be for food.

⁸“‘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.

⁹Then you shall sound the loud trumpet on the tenth day of the seventh month. On the Day of Atonement you shall sound the trumpet throughout all your land.
