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