"lord of breaches", where Jehovah broke forth on David's enemies, the Philistines, as a breach ("bursting forth") of waters (2 Samuel 5:20; 1 Chronicles 14:11). Compare Isaiah 28:21, "Mount Perazim"; once the idol Baal's high place, henceforth it was to be noted for Jehovah's bursting forth on David's idolatrous foes.
