2 Samuel 5:17-19

American Standard Version

¹⁷ And when the Philistines heard that they had anointed David king over Israel, all the Philistines went up to seek David; and David heard of it, and went down to the stronghold. ¹⁸ Now the Philistines had come and spread themselves in the valley of Rephaim. ¹⁹ And David inquired of Jehovah, saying, Shall I go up against the Philistines? wilt thou deliver them into my hand? And Jehovah said unto David, Go up; for I will certainly deliver the Philistines into thy hand.
