12all the Levitical singers —Asaph, Heman, Jeduthun, and their sons and relatives — stood on the east side of the altar, dressed in fine linen and playing cymbals, harps, and lyres, accompanied by 120 priests sounding trumpets.
13The trumpeters and singers joined together to praise and thank the LORD with one voice. They lifted up their voices, accompanied by trumpets, cymbals, and musical instruments, in praise to the LORD:
“For He is good;
His loving devotion endures forever.” And the temple, the house of the LORD, was filled with a cloud
