2 Samuel 5:18

16Elishama, Eliada, and Eliphelet.

17When the Philistines heard that they had anointed David king over Israel, all the Philistines went up to seek David, but David heard about it and went down to the stronghold.

18Now the Philistines had come and spread themselves in the valley of Rephaim.

19David inquired of the LORD, saying, “Shall I go up against the Philistines? Will you deliver them into my hand?” The LORD said to David, “Go up; for I will certainly deliver the Philistines into your hand.”

20David came to Baal Perazim, and David struck them there. Then he said, “The LORD has broken my enemies before me, like the breach of waters.” Therefore he called the name of that place Baal Perazim.
