mount of breaches, only in Isa 28:21. It is the same as BAAL-PERAZIM (q.v.), where David gained a victory over the Philistines (2Sa 5:20).
And David went to Baal-perazim, and overcame them there; and he said, The Lord has let the forces fighting against me be broken before me as a wall is broken by rushing waters. So that place was named Baal-perazim.
For the Lord will come up as on Mount Perazim, he will be moved to wrath as in the valley of Gibeon; so that he may do his work--strange is his work; and give effect to his act--unnatural is his act.
