Isaiah 6:1-6 New King James Version (NKJV)
Isaiah Called to Be a Prophet
6 In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lifted up, and the train of His robe filled the temple. 2 Above it stood seraphim; each one had six wings: with two he covered his face, with two he covered his feet, and with two he flew. 3 And one cried to another and said:
“Holy, holy, holy is the Lord of hosts;
4 And the posts of the door were shaken by the voice of him who cried out, and the house was filled with smoke.
5 So I said:
“Woe is me, for I am [a]undone!
6 Then one of the seraphim flew to me, having in his hand a live coal which he had taken with the tongs from the altar.
