After this, the armies of the Moabites, Ammonites, and some of the Meunites declared war on Jehoshapat. (v. 1) NLT
“O Our God, wont’ you stop them? We are powerless against this might army that is about to attack us. We do not know what to do, but we are looking to You for help.”
As all the men of Judah stood before the Lord, with their little ones, wives, and children, the Spirit of the Lord cam upon one of the men standing there. His name was Jahaziel, son of Zechariah, the son of Beniah, son of Jeiel, son of Mattaniah, a Levite who was a descendant of Asaph.
He said, “Listen, all you people of of Judah and Jerusalem! Listen, King Jehoshapat! This is what the Lord says: Do not be afraid! Don’t be discouraged by this might army, for the battle is not yours, but God’s.” (vv 13-15, NLT)
After consulting the people, the king appointed singers to walk ahead of the army, singing to the Lord and praising Him for his holy splendor. This is what they sang:
“Give thanks to the Lord, His faithfulness endures forever!”
At that very moment they began to sing and give praise, the Lord caused the armies of Ammon, Moab and Mount Sier to start fighting among themselves. The armies of Moab and Ammon turned against their allies from Mount Seir, and killed every one of them. After they had destroyed the army of Seir , they began attacking each other. So when the army of Judah arrived at the lookout point in the wilderness, all they saw were dead bodies lying on the ground as far as they could see. Not a single one of the enemy had escaped. (vv. 21-4, NLT)
