2 Chronicles 20:12-20

12O our God, will You not judge them? For we have no power against this great multitude that is coming against us; nor do we know what to do, but our eyes are upon You.”

13Now all Judah, with their little ones, their wives, and their children, stood before the Lord.

14Then the Spirit of the Lord came upon Jahaziel the son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah, a Levite of the sons of Asaph, in the midst of the assembly.

15And he said, “Listen, all you of Judah and you inhabitants of Jerusalem, and you, King Jehoshaphat! Thus says the Lord to you: ‘Do not be afraid nor dismayed because of this great multitude, for the battle is not yours, but God’s.

16Tomorrow go down against them. They will surely come up by the Ascent of Ziz, and you will find them at the end of the brook before the Wilderness of Jeruel.

17You will not need to fight in this battle. Position yourselves, stand still and see the salvation of the Lord, who is with you, O Judah and Jerusalem!’ Do not fear or be dismayed; tomorrow go out against them, for the Lord is with you.”

18And Jehoshaphat bowed his head with his face to the ground, and all Judah and the inhabitants of Jerusalem bowed before the Lord, worshiping the Lord.

19Then the Levites of the children of the Kohathites and of the children of the Korahites stood up to praise the Lord God of Israel with voices loud and high.

20So they rose early in the morning and went out into the Wilderness of Tekoa; and as they went out, Jehoshaphat stood and said, “Hear me, O Judah and you inhabitants of Jerusalem: Believe in the Lord your God, and you shall be established; believe His prophets, and you shall prosper.”
