Leviticus 25:5

2 Speak unto the children of Israel, and say unto them, When ye come into the land which I give you, then shall the land keep a sabbath unto Jehovah.

3 Six years thou shalt sow thy field, and six years thou shalt prune thy vineyard, and gather in the fruits thereof;

4 but in the seventh year shall be a sabbath of solemn rest for the land, a sabbath unto Jehovah: thou shalt neither sow thy field, nor prune thy vineyard.

5 That which groweth of itself of thy harvest thou shalt not reap, and the grapes of thy undressed vine thou shalt not gather: it shall be a year of solemn rest for the land.

6 And the sabbath of the land shall be for food for you; for thee, and for thy servant and for thy maid, and for thy hired servant and for thy stranger, who sojourn with thee.

7 And for thy cattle, and for the beasts that are in thy land, shall all the increase thereof be for food.

8 And thou shalt number seven sabbaths of years unto thee, seven times seven years; and there shall be unto thee the days of seven sabbaths of years, even forty and nine years.
