2 Samuel 6:15

So David and all the house of Israel brought up the ark of the LORD with shouting, and with the sound of the trumpet.

Ver. 15. With shouting.] And singing of psalms, 1Ch 16:8 which although they did with all their might, yet no man was wearied out, as Josephus a here noteth; much less exanimated and killed outright with vehemency of singing, as Paulus Diaconus b saith that eighty men were at Rome, by singing Gregory the Great's litanies, in the time when a great plague raged there.
