“For the children of Ammon and Moab stood up against the inhabitants of mount Seir, utterly to slay and destroy them: and when they had made an end of the inhabitants of Seir, every one helped to destroy another.”
King James Version (KJV)
20:21 Consulted - Jehoshaphat called a counsel of war, and it was resolved, to appoint singers to go out before the army, who had nothing to do, but to praise God, to praise his holiness, which is his beauty, to praise him as they did in the temple, that beauty of holiness. By this strange advance to the field of battle, Jehoshaphat shewed his firm reliance on the word of God, which enabled him to triumph before the battle, to animate his own men and confound the enemy.
20:22 To sing - So acceptable are the fervent prayers of God's people to God, and so terrible to their enemies. Ambushments - Or, liers in wait, either the holy angels, who appeared in the shape of men, and possibly put on the appearances and visages of the Moabites or Ammonites, and in that shape slew the rest, who supposing this slaughter to be done by a part of their own army, fell upon them, and so broke forth into mutual slaughters. Or, God raised jealousies and animosities among themselves, which broke forth, first into secret ambushments, which one party laid for another, and then into open hostilities to their utter destruction. So vain are all mens attempts against God, who needs none to destroy his enemies but themselves, and their own mistakes, and passions, which he can, when he pleaseth, arm against them.
20:24 The watch tower - Which stood upon the cliff of Ziz, mentioned ver.#16|, and looked toward the wilderness, where their enemies lay encamped, whose numbers, and order, and condition, they could descry from thence.
20:25 Jewels - Which they brought with them to corrupt any of Jehoshaphat's officers as they saw occasion: to procure necessaries for their vast army from time to time: and because they came as to triumph rather than to fight, being confident of the victory because of their numbers, and especially because they thought to surprize Jehoshaphat ere he could make any considerable preparations against them; God also permitting them to be puffed up to their own destruction.
