2 Samuel 5:22-25

²²The Philistines came up yet again, and spread themselves in the valley of Rephaim. ²³When David inquired of Yahweh, he said, You shall not go up: make a circuit behind them, and come on them over against the mulberry-trees. ²⁴It shall be, when you hear the sound of marching in the tops of the mulberry-trees, that then you shall bestir yourself; for then is Yahweh gone out before you to strike the host of the Philistines. ²⁵David did so, as Yahweh commanded him, and struck the Philistines from Geba until you come to Gezer.
