Matthew Henry on 2 Chronicles 20:14-19
We have here God's gracious answer to Jehoshaphat's prayer; and it was a speedy answer. While he was yet speaking God heard: before the congregation was dismissed they had assurance given them that they should be victorious; for it is never in vain to seek God. 1. The spirit of prophecy came upon a Levite that was present, not in any place of eminency, but in the midst of the congregation, Ch2 20:14. The Spirit, like the wind, blows where and on whom he listeth. He was of the sons of Asaph, and therefore one of the singers; on that office God would put an honour.

Jehoshaphat bowed his head . . . and all Judah, &c.--This attitude was expressive of reverence to God and His Word, of confidence in His promise, and thankfulness for so extraordinary a favor.
Adam Clarke on 2 Chronicles 20:17
For the Lord will be with you - "The Word of the Lord shall be your Helper." - Targum.
John Gill on 2 Chronicles 20:18

and all Judah, and the inhabitants of Jerusalem, fell before the Lord, worshipping him; adoring his goodness to them, in imitation of their king.

The Lord's answer by the prophet Jahaziel. - Ch2 20:14. In the midst of the assembly the Spirit of the Lord came upon Jahaziel, a Levite of the sons of Asaph, and promised miraculous assistance to king and people. Jahaziel's descent is traced back for five generations to the Levite Mattaniah of the sons of Asaph. This Mattaniah is not the same person as the Mattaniah in Ch1 25:4, Ch1 25:16, who lived in David's time, for he belonged to the sons of Heman; but perhaps (as Movers conjectures, S. 112) he is identical with the Asaphite Nethaniah, Ch1 25:2, Ch1 25:12, since מ and נ might easily be confounded.
Ch2 20:15
Jehaziel announced to the king and people that they need not fear before the gr…
