and all the Levitical singers--Asaph, Heman, Jeduthun, their sons, their brothers, dressed [in] fine linen, with cymbals, harps, and stringed instruments--[they] were standing to the east of the altar. And with them outside [were] one hundred and twenty priests [who were] trumpet blowers.
13
And it was the primary [duty] of the trumpeters and singers to make themselves heard [with] one voice, to praise and give thanks to Yahweh. And when a sound from the trumpets, cymbals, and other instruments of song was raised to Yahweh--for he [is] good, because his loyal love [is] everlasting--then the house, the house of Yahweh, was filled with a cloud.
14
And the priests were not able to stand to minister because of the cloud, for the glory of Yahweh filled the house of God.
