12 'O our God, dost Thou not execute judgment upon them? for there is no power in us before this great multitude that hath come against us, and we know not what we do, but on Thee 'are' our eyes.' 13 And all Judah are standing before Jehovah, also their infants, their wives, and their sons.

14 And upon Jahaziel, son of Zechariah, son of Benaiah, son of Jeiel, son of Mattaniah, the Levite, of the sons of Asaph, hath the Spirit of Jehovah been, in the midst of the assembly, 15 and he saith, 'Attend, all Judah, and ye inhabitants of Jerusalem, and O king Jehoshaphat, Thus said Jehovah to you, Ye fear not, nor are afraid of the face of this great multitude, for not for you 'is' the battle, but for God. 16 To-morrow, go ye down against them, lo, they are coming up by the ascent of Ziz, and ye have found them in the end of the valley, the front of the wilderness of Jeruel. 17 Not for you to fight in this; station yourselves, stand, and see the salvation of Jehovah with you, O Judah and Jerusalem—be not afraid nor fear ye—to-morrow go out before them, and Jehovah 'is' with you.' 18 And Jehoshaphat boweth—face to the earth—and all Judah and the inhabitants of Jerusalem have fallen before Jehovah, to bow themselves to Jehovah. 19 And the Levites, of the sons of the Kohathites, and of the sons of the Korhites, rise to give praise to Jehovah, God of Israel, with a loud voice on high.

20 And they rise early in the morning, and go out to the wilderness of Tekoa, and in their going out Jehoshaphat hath stood and saith, 'Hear me, O Judah, and inhabitants of Jerusalem, remain stedfast in Jehovah your God, and be stedfast; remain stedfast in His prophets, and prosper.'

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.
