Breaking Out by Dr. Tom Leuther

When the Philistines heard that David had been anointed king over Israel, they went up in full force to search for him, but David heard about it and went down to the stronghold. Now the Philistines had come and spread out in the Valley of Rephaim; so David inquired of the Lord, “Shall I go and attack the Philistines? Will you deliver them into my hands?” The Lord answered him, “Go, for I will surely deliver the Philistines into your hands.” 2 Samuel 5:17-19 (NIV)
