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.
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.
