1 Chronicles 14:8-16

8And when the Philistines heard that David was anointed king over all Israel, all the Philistines went up to seek David: and David heard of it, and went out against them. 9Now the Philistines had come and made a raid in the valley of Rephaim. 10And David inquired of God, saying, Shall I go up against the Philistines? and wilt thou deliver them into my hand? And Jehovah said unto him, Go up; for I will deliver them into thy hand. 11So they came up to Baal-perazim, and David smote them there; and David said, God hath broken mine enemies by my hand, like the breach of waters. Therefore they called the name of that place Baal-perazim. 12And they left their gods there; and David gave commandment, and they were burned with fire.

13And the Philistines yet again made a raid in the valley. 14And David inquired again of God; and God said unto him, Thou shalt not go up after them: turn away from them, and come upon them over against the mulberry-trees. 15And it shall be, when thou hearest the sound of marching in the tops of the mulberry-trees, that then thou shalt go out to battle; for God is gone out before thee to smite the host of the Philistines. 16And David did as God commanded him: and they smote the host of the Philistines from Gibeon even to Gezer.
