2nd Chronicles: Chapter 20, Verse 1-18, 20-27Verse 1-4: The people of Moab, the people of Ammon and the people of Mount Seir came to battle against Jehoshaphat. Then some came and told Jehoshaphat saying, “A great multitude is coming against you from beyond the sea, from Syria and they are in En Gedi. And King Jehoshaphat feared and set himself to seek the Lord and proclaimed a fast throughout all Judah. So Judah gathered together to ask help from the Lord. From all the cities of Judah they came to seek the Lord.
Verse 5-9: Then Jehoshaphat stood in the assembly of Judah and Jerusalem, in the house of the Lord before the new court and said, “O Lord God of our fathers, are You not God in heaven, and do You not rule over all the kingdoms of the nations; and in Your hand is there not power and might, so that no one is able to withstand You? Are You not our God, who drove out the inhabitants of this land before Your people Israel, and gave it to the descendants of Abraham Your friend forever? They dwell in it and have built You a sanctuary in it for Your name, saying “If disaster comes upon us – sword, judgment, pestilence or famine – we will stand before this temple and in Your presence (for Your name is in this temple) and cry out to You in our affliction and You will hear and save.”
Verse 10-12: “And now, here are the people of Ammon, Moab and Mount Seir – whom You would not let Israel invade them when they came out of the land of Egypt, but they turned from them and did not destroy them – here they are, rewarding us by coming to throw us out of Your possession which You have given us to inherit. O our God, will You not judge them? For we have no power against this great multitude that is coming against us; nor do we know what to do, but our eyes are upon You.”
Verse 13-15 & 17-18: Now all Judah, with their little ones, their wives and their children, stood before the Lord. Then the Spirit of the Lord came upon Jahaziel, the prophet in the midst of the assembly. And he said, “Listen, all you of Judah and you inhabitants of Jerusalem, and you, King Jehoshaphat! Thus say the Lord t
o you: ‘Do not be afraid nor dismayed because of this great multitude, for the battle is not yours, but God’s. You will not need to fight in this battle. Position yourselves, stand still and see the salvation of the Lord, who is with you, O Judah and Jerusalem. Do not fear or be dismayed; tomorrow go out against them, for the Lord is with you.” Jehoshaphat bowed his head with his face to the ground, and all Judah and the inhabitants of Jerusalem bowed before the Lord, worshiping the Lord. 
Verse 20-22: So they rose early in the morning and went out into the Wilderness of Tekoa; and as they went out, Jehoshaphat stood and said, “Hear me, O Judah and you inhabitants of Jerusalem: Believe in the Lord your God, and you shall be established; believe His prophets, and you shall be prosper.” And when he had consulted with the people, he appointed those who should sing to the Lord, and who should praise the beauty of holiness, as they went out before the army and were saying: “Praise the Lord, For His mercy endures forever.” Now when they began to sing and to praise, the Lord set ambushed against the people of Ammon, Moab and Mount Seir, who had come against Judah; and they were defeated.
Verse 23: For the people of Ammon and Moab stood up against the inhabitants of Mount Seir to utterly kill and destroy them. And when they had made an end of the inhabitants of Seir, they helped to destroy one another.

Verse 24-25: So when Judah came to a place overlooking the wilderness, they look toward the multitude; and they were their dead bodies; fallen on the earth. No one had escaped. When King Jehoshaphat and his people came to take away their spoil, they found among them an abundance of valuables on the dead bodies, and precious jewelry, which they stripped off for themselves, more than they could carry away; and they were three days gathering the spoil because there was so much.Verse 26-28: And on the fourth day they assembled in the Valley of Berachah, for there they blessed the Lord; therefore the name of that place was called The Valley of Berachah until this day. Then they returned, every man of Judah and Jerusalem, with King Jehoshaphat in front of them, to go back to Jerusalem with joy, for the Lord had made them rejoice over their enemies.
