2 Chronicles 20:21-22

21 After consulting the people, Jehoshaphat appointed men to sing to the LORD and to praise him for the splendor of his holiness as they went out at the head of the army, saying: "Give thanks to the LORD, for his love endures forever." 22 As they began to sing and praise, the LORD set ambushes against the men of Ammon and Moab and Mount Seir who were invading Judah, and they were defeated.

A couple of thoughts:

1. "Jehoshaphat appointed men to sing to the LORD..."–I took a quick survey in all three of my choirs yesterday to see if their congregations had any controversy with either women being choir directors or women being in their church choirs. I even asked if their was any talk that women shouldn't organists in their churches. Thankfully, it seems this misapplication of scripture has died down, at least in our area, or my students are oblivious to it.
2. "...to sing...as they went out at the head of the army"–this reminded me of what Henry V told his army to do after they defeated the French in the Battle of Agincourt (1415) during the Hundred Years' War. Henry V, according to William Shakespeare, told his troops to sing "Non nobis" (Not to us--Ps. 115) and "Te Deum" (To you, O God) after they routed the French, having been outnumbered 10 to 1.
