2 Samuel 5:22-25

22 ¶ And the Philistines came up yet again, and spread themselves in the valley of Rephaim. 23 And when David inquired of the Lord, he said, Thou shalt not go up; but fetch a compass behind them, and come upon them over against the mulberry trees. 24 And let it be, when thou hearest the sound of a going in the tops of the mulberry trees, that then thou shalt bestir thyself: for then shall the Lord go out before thee, to smite the host of the Philistines. 25 And David did so, as the Lord had commanded him; and smote the Philistines from Geba until thou come to Gazer.
