1 Kings 20:41

And he hasted, and took the ashes away from his face; and the king of Israel discerned him that he was of the prophets.

The verse belongs to the account of the defeat of Ben-hadad, king of Syria. The events of that chapter were another effort by God to win the weak Ahab. In context, the story of 1 Kings 20:35-43 shows that being occupied here and there and thereby neglecting an assigned duty to guard what was entrusted brings serious consequences, as seen in the servant's admission that distraction allowed the man in his charge to disappear. Applied to soul saving, it warns against neglecting personal work for others.
