2 Chronicles
Chapters 20:1-4
English Revised Version
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 be in Hazazon-tamar (the same is En-gedi).
3And Jehoshaphat feared, and set himself to seek unto the LORD; and he proclaimed a fast throughout all Judah.
4And Judah gathered themselves together, to seek help of the LORD: even out of all the cities of Judah they came to seek the LORD.
