Then the commanders of the Philistines went out to battle, and it happened as often as they went out, that David behaved himself more insightfully than all the servants of Saul. So his name was highly esteemed.
Now there was an evil spirit from Yahweh on Saul as he was sitting in his house with his spear in his hand, and David was playing the harp with his hand.
So David and his men went to Keilah and fought with the Philistines; and he led away their livestock and struck them with a great slaughter. Thus David saved the inhabitants of Keilah.
