20 And early in the morning they got up and went out to the waste land of Tekoa: and when they were going out, Jehoshaphat took his station and said to them, Give ear to me, O Judah and you people of Jerusalem: have faith in the Lord your God and you will be safe; have faith in his prophets and all will go well for you. 21 And after discussion with the people, he put in their places those who were to make melody to the Lord, praising him in holy robes, while they went at the head of the army, and saying, May the Lord be praised, for his mercy is unchanging for ever.

Commentary on 2 Chronicles 20:20-30
(Read 2 Chronicles 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.
