12 O our God, won't you stop them? We are powerless against this mighty army that is about to attack us. We do not know what to do, but we are looking to you for help." 13 As all the men of Judah stood before the Lord with their little ones, wives, and children,

14 the Spirit of the Lord came upon one of the men standing there. His name was Jahaziel son of Zechariah, son of Benaiah, son of Jeiel, son of Mattaniah, a Levite who was a descendant of Asaph. 15 He said, "Listen, all you people of Judah and Jerusalem! Listen, King Jehoshaphat! This is what the Lord says: Do not be afraid! Don't be discouraged by this mighty army, for the battle is not yours, but God's. 16 Tomorrow, march out against them. You will find them coming up through the ascent of Ziz at the end of the valley that opens into the wilderness of Jeruel. 17 But you will not even need to fight. Take your positions; then stand still and watch the Lord 's victory. He is with you, O people of Judah and Jerusalem. Do not be afraid or discouraged. Go out against them tomorrow, for the Lord is with you!" 18 Then King Jehoshaphat bowed low with his face to the ground. And all the people of Judah and Jerusalem did the same, worshiping the Lord . 19 Then the Levites from the clans of Kohath and Korah stood to praise the Lord, the God of Israel, with a very loud shout.

20 Early the next morning the army of Judah went out into the wilderness of Tekoa. On the way Jehoshaphat stopped and said, "Listen to me, all you people of Judah and Jerusalem! Believe in the Lord your God, and you will be able to stand firm. Believe in his prophets, and you will succeed."

Commentary on 2 Chronicles 20:1-13

(Read 2 Chronicles 20:1-13)

In all dangers, public or personal, our first business should be to seek help from God. Hence the advantage of days for national fasting and prayer. From the first to the last of our seeking the Lord, we must approach him with humiliation for our sins, trusting only in his mercy and power. Jehoshaphat acknowledges the sovereign dominion of the Divine Providence. Lord, exert it on our behalf. Whom should we seek to, whom should we trust to for relief, but the God we have chosen and served. Those that use what they have for God, may comfortably hope he will secure it to them. Every true believer is a son of Abraham, a friend of God; with such the everlasting covenant is established, to such every promise belongs. We are assured of God's love, by his dwelling in human nature in the person of the Saviour. Jehoshaphat mentions the temple, as a token of God's favourable presence. He pleads the injustice of his enemies. We may well appeal to God against those that render us evil for good. Though he had a great army, he said, We have no might without thee; we rely upon thee.

Commentary on 2 Chronicles 20:14-19

(Read 2 Chronicles 20:14-19)

The Spirit of prophecy came upon a Levite in the midst of the congregation. The Spirit, like the wind, blows where and on whom He listeth. He encouraged them to trust in God. Let the Christian soldier go out against his spiritual enemies, and the God of peace will make him more than a conqueror. Our trials will prove our gain. The advantage will be all our own, but the whole glory must be given to God.

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.
