12. with both the Levites and the singing men, that is, those who were under Asaph, and those who were under Heman, and those who were under Jeduthun, with their sons and brothers, clothed in fine linen, sounded out with cymbals, and psalteries, and harps, standing toward the eastern side of the altar. And with them were one hundred twenty priests, sounding out with trumpets.
13. And when they all sounded out together, with trumpets, and voice, and cymbals, and pipes, and with various kinds of musical instruments, lifting their voice on high, the sound was heard from far away, so that when they had begun to praise the Lord, and to say, "Confess to the Lord, for he is good; for his mercy is eternal," the house of God was filled with a cloud.
14. Neither were the priests able to stand and to minister, because of the cloud. For the glory of the Lord had filled the house of God.
