Isaiah 6:1-4 ESV
In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple. Above him stood the seraphim. Each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew. And one called to another and said:
“Holy, holy, holy is the LORD of hosts;
the whole earth is full of his glory!”
And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke.
