Isaiah 6:2-7 And seraphs stood around him, each having six wings; and with two they covered the face, and with two they covered the feet, and two they used in flying.

Thomson⁽ⁱ⁾ ² And seraphs stood around him, each having six wings; and with two they covered the face, and with two they covered the feet, and two they used in flying. ³ And they cried one to another and said, "Holy, holy, holy is the Lord of Hosts; the whole earth is filled with his glory." ⁴ And the lintel of the door was shaken with the sound of their cry, and the house was filled with smoke. ⁵ Whereupon I said, Ah! Woe is me! [for I was confounded] for being a man, and having unclean lips; and dwelling among a people of unclean lips, I have seen with mine eyes the king the Lord of Hosts. ⁶ Then one of the seraphs was sent to me and he had in his hand a live coal which he had taken from the altar with the tongs. ⁷ And having touched my lips he said, Behold this hath touched thy lips, and it will take away thine iniquities and purge away thy sins.
