'Sing' in the Bible

After he had consulted with the people, Jehoshaphat appointed some choir members to sing to the LORD and to praise him in sacred splendor as they marched out in front of the armed forces. They kept saying "Give thanks to the LORD, because his gracious love is eternal!"

Right on time, as they began to sing and praise, the LORD ambushed the Ammonites, Moabites, and the inhabitants of Mount Seir who had attacked Judah, and they were defeated.

King Hezekiah and his officials ordered the descendants of Levi to sing praises to the LORD based on psalms that had been written by David and Asaph the seer. So they all joyfully sang praises, bowed low, and worshipped.
