Achish said to David, "In that case I will make you the captain of my body-guard from this time on."
And David arose, and he passed over with the six hundred men that were with him unto Achish, king of Gath.
Achish trusted David, and said: He has already dwelt with me for a time, for years; to this day I have found nothing in him.
What a picture of a furious madman is the description of his conduct when Achish's servants came to arrest him.
If this was the Achish, son of Maoch, with whom David had taken refuge fifty years before, he must now have been a very old man.
