2 Chronicles 20:2-6

Then some came and reported to Jehoshaphat, saying, “A great multitude is coming against you from beyond the sea, from Aram; and behold, they are in Hazazon-tamar (that is Engedi).”

Jehoshaphat was afraid and turned his attention to seek the Lord; and he proclaimed a period of fasting throughout Judah.

So Judah gathered together to seek help from the Lord; they even came from all the cities of Judah to seek the Lord. Jehoshaphat’s Prayer

Then Jehoshaphat stood in the assembly of Judah and Jerusalem, in the house of the Lord in front of the new courtyard;

and he said, “Lord, God of our fathers, are You not God in the heavens? And are You not ruler over all the kingdoms of the nations? Power and might are in Your hand so that no one can stand against You.
