King Jehoshaphat sends out the choir in front of the army

A group of musicians and singers leads a vast army over a rocky desert in early morning. “Then he [King Jehoshaphat of Judah] consulted with the people and appointed some to sing for the Lord and some to praise the splendor of his holiness. When they went out in front of the armed forces, they kept singing: Give thanks to the Lord, for his faithful love endures forever.” (2 Chronicles 20:21)
