2 Chronicles 20:1-6

1And 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. 2Then 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). 3And Jehoshaphat feared, and set himself to seek unto Jehovah; and he proclaimed a fast throughout all Judah. 4And Judah gathered themselves together, to seek help of Jehovah: even out of all the cities of Judah they came to seek Jehovah.

5And Jehoshaphat stood in the assembly of Judah and Jerusalem, in the house of Jehovah, before the new court; 6and 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.
