1 Chronicles 14:8-10

When the Philistines heard that David had been anointed king over all Israel, they mobilized all their forces to capture him. But David was told they were coming, so he marched out to meet them. The Philistines arrived and made a raid in the valley of Rephaim. So David asked God, “Should I go out to fight the Philistines? Will you hand them over to me?” The LORD replied, “Yes, go ahead. I will hand them over to you.”
