7Now a certain man of the servants of Saul was there that day, kept back before the Lord; his name was Doeg, an Edomite, the strongest of Saul's runners.
8And David said to Ahimelech, Have you no sword or spear with you here? for I have come without my sword and other arms, because the king's business had to be done quickly.
9And the priest said, The sword of Goliath the Philistine, whom you put to death in the valley of Elah, is here folded in a cloth at the back of the ephod: take that, if you will, for there is no other sword here. And David said, there is no other sword like that; give it to me.
10Then David got up and went in flight that day for fear of Saul, and went to Achish, the king of Gath.
11And the servants of Achish said to him, Is not this David, the king of the land? did they not make songs about him in their dances, saying, Saul has put to death thousands, and David tens of thousands?
12And David took these words to heart, fearing Achish, the king of Gath.
13So changing his behaviour before them, he made it seem as if he was off his head, hammering on the doors of the town, and letting the water from his mouth go down his chin.
