2 Chronicles 20:26-30

On the fourth day they gathered in the Valley of Blessing, which got its name that day because the people praised and thanked the LORD there. It is still called the Valley of Blessing today. Then all the men returned to Jerusalem, with Jehoshaphat leading them, overjoyed that the LORD had given them victory over their enemies. They marched into Jerusalem to the music of harps, lyres, and trumpets, and they proceeded to the Temple of the LORD. When all the surrounding kingdoms heard that the LORD himself had fought against the enemies of Israel, the fear of God came over them. So Jehoshaphat’s kingdom was at peace, for his God had given him rest on every side.
