None that makes much military sense, if using traditional tactics is the key to victory. The genius of God’s ways is that they are not our ways. Tactics that should fail do in fact succeed as God’s way of showing His power in our weakness. At Jericho, the victory was preceded by priests blowing horns and circling the city seven times. Against the Philistines, David’s single slingshot led to an amazing victory.
Yet, on second look, perhaps Jehoshaphat’s plan was not without military cunning. As music for motivation and bravery. The roll of drums or bugle blast can stir the soldier to selfless action. The Normandy invasion of World War II is associated with the first movement of Beethoven’s Fifth Symphony. Why shouldn’t Jehoshaphat’s army hear the sound of many voices praising the God of protection and might? If you were an archer in the ranks that day, wouldn’t you want a little music to calm your jitters, make you brave, and remind you of God’s power.
2 CHRONICLES 20:21 – 21 After consulting the people, Jehoshaphat appointed men to sing to the Lord and to praise him for the splendor of his[a] holiness as they went out at the head of the army, saying:
“Give thanks to the Lord,
for his love endures forever.”
