He was aware, however, that there was little moral discipline and restraint left in them. Hence he hit upon this device to distinguish the worthy from the worthyless.

None of the Israelites had the courage to take up the challenge. On seeing this, David took on Goliath in a duel and slew him. From then on, David could do no wrong in the eyes of the Israelites.
