Isaiah 6:1-4 (NRSV)

1 In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lofty; and the hem of his robe filled the temple. 2 Seraphs were in attendance above him; each had six wings: with two they covered their faces, and with two they covered their feet, and with two they flew.
3 And one called to another and said:

“Holy, holy, holy is the LORD of hosts;
the whole earth is full of his glory.”

4 The pivots on the thresholds shook at the voices of those who called, and the house filled with
smoke.
