I Chronicles 14:8-10

Now when the Philistines heard that David had been anointed king over all Israel, all the Philistines went up to search for David. And David heard of it and went out against them. Then the Philistines went and made a raid on the Valley of Rephaim. And David inquired of God, saying, “Shall I go up against the Philistines? Will You deliver them into my hand?” The LORD said to him, “Go up, for I will deliver them into your hand.”
