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.
Ten men ... said unto Ishmael, Slay us not; for we have treasures. It was customary to hide grain in cavities underground in troubled times. "We have treasures," which we will give if our lives be spared.
He ... slew them not - (Proverbs 13:8, "The ransom of a man's life are his riches"). Ishmael's avarice and needs overcame his cruelty.
