2 Chronicles 20:1-15

And it came to pass after this, that the children of Moab, and the children of Ammon, and with them some of the Ammonites, came against Jehoshaphat to battle. Then there came some that told Jehoshaphat, saying, There cometh a great multitude against thee from beyond the sea from Syria; and, behold, they are in Hazazon-tamar (the same is En-gedi). And Jehoshaphat feared, and set himself to seek unto Jehovah; and he proclaimed a fast throughout all Judah. And Judah gathered themselves together, to seek help of Jehovah: even out of all the cities of Judah they came to seek Jehovah. And Jehoshaphat stood in the assembly of Judah and Jerusalem, in the house of Jehovah, before the new court; and he said, O Jehovah, the God of our fathers, art not thou God in heaven? and art not thou ruler over all the kingdoms of the nations? and in thy hand is power and might, so that none is able to withstand thee. Didst not thou, O our God, drive out the inhabitants of this land before thy people Israel, and give it to the seed of Abraham thy friend for ever? And they dwelt therein, and have built thee a sanctuary therein for thy name, saying, If evil come upon us, the sword, judgment, or pestilence, or famine, we will stand before this house, and before thee (for thy name is in this house), and cry unto thee in our affliction, and thou wilt hear and save. And now, behold, the children of Ammon and Moab and mount Seir, whom thou wouldest not let Israel invade, when they came out of the land of Egypt, but they turned aside from them, and destroyed them not; behold, how they reward us, to come to cast us out of thy possession, which thou hast given us to inherit. O our God, wilt thou not judge them? for we have no might against this great company that cometh against us; neither know we what to do: but our eyes are upon thee. And all Judah stood before Jehovah, with their little ones, their wives, and their children. Then upon Jahaziel the son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah, the Levite, of the sons of Asaph, came the Spirit of Jehovah in the midst of the assembly; and he said, Hearken ye, all Judah, and ye inhabitants of Jerusalem, and thou king Jehoshaphat: Thus saith Jehovah unto you, Fear not ye, neither be dismayed by reason of this great multitude; for the battle is not yours, but God’s.
