2 Chronicles 20:1-4

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