²² Once more the Philistines came up. They spread out in the Valley of Rephaim. ²³ So David asked the Lord for advice. The Lord answered, “Do not go straight up. Instead, circle around behind them. Attack them in front of the poplar trees. ²⁴ Listen for the sound of marching in the tops of the trees. Then move quickly. The sound will mean that I have gone out in front of you. I will strike down the Philistine army.”
