20:22 And when they began to sing and to praise, the LORD set ambushments against the children of Ammon, Moab, and {o} mount Seir, which were come against Judah; and they were smitten.
(o) Meaning, the Idumeans who dwelt in mount Seir.
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.
20:20-30 Jehoshaphat exhorted his troops to firm faith in God. Faith inspires a man with true courage; nor will any thing help more to the establishing of the heart in shaking times, than a firm belief of the power, and mercy, and promise of God. In all our trust in the Lord, and our praises of him, let us especially look at his everlasting mercy to sinners through Jesus Christ. Never was an army so destroyed as that of the enemy. Thus God often makes wicked people destroy one another. And never was a victory celebrated with more solemn thanksgivings.
