1 Chronicles 14:8-10

When the Philistines heard that David had been anointed king over all Israel, they went up in full force to search for him, but David heard about it and went out to meet them. Now the Philistines had come and raided the Valley of Rephaim; so David inquired of God: “Shall I go and attack the Philistines? Will you deliver them into my hands?” The LORD answered him, “Go, I will deliver them into your hands.”
