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. 22 And at the first notes of song and praise the Lord sent a surprise attack against the children of Ammon and Moab and the people of Mount Seir, who had come against Judah; and they were overcome. 23 And the children of Ammon and Moab made an attack on the people of Mount Seir with a view to their complete destruction; and when they had put an end to the people of Seir, everyman's hand was turned against his neighbour for his destruction. 24 And Judah came to the watchtower of the waste land, and looking in the direction of the army, they saw only dead bodies stretched on the earth; no living man was to be seen. 25 And when Jehoshaphat and his people came to take their goods from them, they saw beasts in great numbers, and wealth and clothing and things of value, more than they were able to take away; all this they took for themselves, and they were three days getting it away, there was so much. 26 On the fourth day they all came together in the Valley of Blessing, and there they gave blessing to the Lord; for which cause that place has been named the Valley of Blessing to this day. 27 Then all the men of Judah and Jerusalem went back, with Jehoshaphat at their head, coming back to Jerusalem with joy; for the Lord had made them glad over their haters. 28 So they came to Jerusalem with corded instruments and wind-instruments into the house of the Lord. 29 And the fear of God came on all the kingdoms of the lands, when they had news of how the Lord made war on those who came against Israel. 30 So the kingdom of Jehoshaphat was quiet, for the Lord gave him rest on every side.

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.
