(b) It appears that he alludes to the great victory of Jehoshaphat, whom God used without man's help to destroy the enemies, (2 Chronicles 20:20-26); also he is referring to this word Jehoshaphat, which signifies pleading or judgment, because God would judge the enemies of his Church, as he did there.
