And the Philistines came and spread themselves in the valley of Rephaim.

And David enquired of God, saying, Shall I go up against the Philistines? And wilt thou deliver them into mine hand? And the LORD said unto him, Go up; for I will deliver them into thine hand.

So they came up to Baalperazim; and David smote them there. Then David said, God hath broken in upon mine enemies by mine hand like the breaking forth of waters: therefore they called the name of that place Baalperazim.

And the Philistines yet again spread themselves abroad in the valley.

Therefore David enquired again of God; and God said unto him, Go not up after them; turn away from them, and come upon them over against the mulberry trees.

And it shall be, when thou shalt hear a sound of going in the tops of the mulberry trees, that then thou shalt go out to battle: for God is gone forth before thee to smite the host of the Philistines.
