Therefore they shall come and sing in the height of Zion, and shall flow together to the goodness of the LORD, for wheat, and for wine, and for oil, and for the young of the flock and of the herd: and their soul shall be as a watered garden; and they shall not sorrow any more at all.

But ten men were found among them that said unto Ishmael, Slay us not: for we have treasures in the field, of wheat, and of barley, and of oil, and of honey. So he forbare, and slew them not among their brethren.
