The first error of David was his distrust of God at Nob, and his second mistake was his deception before Achish. David had displayed noble traits of character, and his moral worth had won 657 him favor with the people; but as trial came upon him, his faith was shaken, and human weakness appeared. He saw in every man a spy and a betrayer. In a great emergency David had looked up to God with a steady eye of faith, and had vanquished the Philistine giant. He believed in God, he went in His name. But as he had been hunted and persecuted, perplexity and distress had nearly hidden his heavenly Father from his sight.

David begik sin første fejl, da han nærede mistillid til Gud i Nob, og da han bedrog Akisj, fejlede han på ny. David havde vist, at han besad ædle karaktertræk, og hans store tapperhed havde skaffet ham folkets yndest; men da han blev stillet på prøve, vaklede hans tro, og hans menneskelige svaghed kom til syne. Han så en spion og en forræder i hvert eneste menneske. Under en stor krise havde David fæstnet troens øje på Gud og besejret filisternes kæmpe. Han troede på Gud og gik i kamp i hans navn. Men under sin flugt blev han rådvild og modløs og tabte næsten fuldstændig sin himmelske Fader af syne.
