21 so that your days are multiplied, and the days of your sons, on the ground which Jehovah hath sworn to your fathers to give to them, as the days of the heavens on the earth.
21
so that your days and the days of your children may be many in the land the LORD swore to give your ancestors, as many as the days that the heavens are above the earth.
