1 Chronicles 14:13KJV

11So 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.

12And when they had left their gods there, David gave a commandment, and they were burned with fire.

13And the Philistines yet again spread themselves abroad in the valley.

14Therefore 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.

15And it shall be, when thou shalt hear a sound of going in the tops of the mulberry trees, then thou shalt go out to battle: for God is gone forth before thee to smite the host of the Philistines.
