In the year of King Uzziah’s death, I saw the Lord sitting on a high and exalted throne, the edges of his robe filling the temple. Winged creatures were stationed around him. Each had six wings: with two they veiled their faces, with two their feet, and with two they flew about. They shouted to each other, saying:
“Holy, holy, holy is the LORD of heavenly forces! All the earth is filled with God’s glory!”
The doorframe shook at the sound of their shouting, and the house was filled with smoke.
I said, “Mourn for me; I’m ruined! I’m a man with unclean lips, and I live among a people with unclean lips. Yet I’ve seen the king, the LORD of heavenly forces!”
Then one of the winged creatures flew to me, holding a glowing coal that he had taken from the altar with tongs. He touched my mouth and said, “See, this has touched your lips. Your guilt has departed, and your sin is removed.”
Then I heard the Lord’s voice saying, “Whom should I send, and who will go for us?”
I said, “I’m here; send me.”
-Isaiah 6:1-8 (Common English Bible)
