Leviticus 25:3-4

25:3 Six years thou shalt sow thy field, and six years thou shalt prune thy vineyard, and gather in the fruit thereof; 25:4 But in the seventh year shall be a sabbath of rest unto the land, a sabbath for the LORD: thou shalt neither sow thy field, nor prune thy vineyard.

Leviticus 25:11

25:11 A jubile shall that fiftieth year be unto you: ye shall not sow, neither reap that which groweth of itself in it, nor gather [the grapes] in it of thy vine undressed.
