20, 21. as they went forth, Jehoshaphat stood . . . Hear me, O Judah, and ye inhabitants of Jerusalem—probably in the gate of Jerusalem, the place of general rendezvous; and as the people were on the eve of setting out, he exhorted them to repose implicit trust in the Lord and His prophet, not to be timid or desponding at sight of the enemy, but to remain firm in the confident assurance of a miraculous deliverance, without their striking a single stroke.

     21. he appointed singers . . . that they should praise . . . as they went out before the army—Having arranged the line of procession, he gave the signal to move forwards. The Levites led the van with their musical instruments; and singing the 136th Psalm, the people went on, not as an army marching against an enemy, but returning in joyful triumph after a victory.

     2Ch 20:22-30. THE OVERTHROW OF HIS ENEMIES.

     22. when they began to sing and to praise the Lord set ambushments against the children of Ammon, Moab, and Mount Seir—Some think that this was done by angels in human form, whose sudden appearance diffused an uncontrollable panic. Others entertain the more probable opinion that, in the camp of this vast horde, composed of different tribes, jealousies and animosities had sprung up, which led to widespread dissensions and fierce feuds, in which they drew the sword against each other. The consequence was, that as the mutual strife commenced when the Hebrew procession set out from Jerusalem, the work of destruction was completed before Jehoshaphat and his people arrived at the battlefield. Thus easy is it for God to make the wrath of man to praise Him, to confound the counsels of His enemies and employ their own passions in defeating the machinations they have devised for the overthrow of His Church and people.

     24-26. when Judah came toward the watchtower in the wilderness—Most probably the conical hill, Jebel Fereidis, or Frank Mountain, from the summit of which they obtained the first view of the scene of slaughter. Jehoshaphat and his people found the field strewed with dead bodies, so that they had not to fight at all, but rather to take possession of an immense booty, the collection of which occupied three days. On the fourth they set out on their return to Jerusalem in the same order and joyful mood as they came. The place where they mustered previous to departure was, from their public thanksgiving service, called, "The Valley of Berachah" ("benediction"), now Wady Bereikut.
