Ba'al-Perazim (Hebrew Owner of Breakings Through) was a place in ancient Israel.
It was the scene of a victory gained by David over the Philistines (2 Samuel 5:20; 1 Chronicles 14:11). It is called Mount Perazim in Isaiah 28:21. It was near the Valley of Rephaim, west of Jerusalem.
Some scholars suggest a site 4 km northwest of Jerusalem, named Sheikh Bodr, to be identical with Ba'al-Perazim.
It is not certain whether the occurrence in 2 Sam.5:20 name is:
Yoshitaka Kobayashi considers it is an anachronism, but the use of Baal rather than El may indicate a play on an existing local name.
If the reference is to Mt. Perazim in Isaiah 28 then that suggests a mountain with a high ground position for David to attack. Alternatively, since David says "Yahweh burst-through" (פָּרַץ יְהוָה) "like bursting of waters" (פֶרֶץ מָיִם) it may be a reference to waters.
In the Amplified Bible he is called "Baal-perazim" the Master of the breakthrough.
This place name is the origin of term "God of the Breakthrough" in the Gospel music song of that name by Robert Critchley, sung by Lara George.
