2 Chronicles 20:1-6

1It came to pass after this also, that the children of Moab, and the children of Ammon, and with them other beside 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 on this side Syria; and, behold, they be in Hazazon–tamar, which is En–gedi. 3And Jehoshaphat feared, and set himself to seek Yhwh, and proclaimed a fast throughout all Judah.1 4And Judah gathered themselves together, to ask help of Yhwh: even out of all the cities of Judah they came to seek Yhwh.

5And Jehoshaphat stood in the congregation of Judah and Jerusalem, in the house of Yhwh, before the new court, 6And said, O Yhwh God of our fathers, art not thou God in heaven? and rulest not thou over all the kingdoms of the heathen? and in thine hand is there not power and might, so that none is able to withstand thee?
