2 Chronicles 20:21-22—-And when he had consulted with the people, he appointed singers unto the LORD, and that should praise the beauty of holiness, as they went out before the army, and to say, Praise the LORD; for his mercy endureth forever. And when they began to sing and to praise, the LORD set ambushments against the children of Ammon, Moab, and mount Seir, which were come against Judah; and they were smitten.
Jehoshaphat consulted with the people to see if they had the faith to put singers out front. Apparently, they liked the idea. Since they truly believed that God was going to fight the battle and deliver them, they thought they might as well sing His praise for the splendor of His holiness on the way there. This huge men’s choir sang the same chorus that was sung at the dedication of the Temple. It must have been the national anthem of Judah. If you ever attended a Promise Keeper event and heard ten thousands of men sing praises to God, you have a taste of what this must have been like. The praise was not a part of the LORD’s instruction, but it was a natural response when they believed He was delivering them from their enemy. As they sang, the LORD turned the enemy upon one another. There was not one enemy soldier left alive. Judah took three days to gather all the spoils of war. There was more than they could carry away. On the fourth day they held a great praise festival at the Valley of Praise. The people’s response to God’s word in the face of a major threat upon their lives is an example to us. They didn’t mope around or complain and whine, instead, they sang their thanks to God for who He is.
