1st Chronicles Chapter 14 American Standard-ASV1901
And 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.
So 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.
And 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.
