Isaiah 6:2-7 And seraphim stood round about Him; each one had six wings; and with two they covered their face, and with two they covered their feet, and with two they flew.

CAB⁽ⁱ⁾ ² And seraphim stood round about Him; each one had six wings; and with two they covered their face, and with two they covered their feet, and with two they flew. ³ And one cried to the other, and they said, Holy, holy, holy is the Lord of hosts; the whole earth is full of His glory. ⁴ And the doorpost shook at the voice they uttered, and the house was filled with smoke. ⁵ And I said, Woe is me, for I am pricked to the heart; for being a man, and having unclean lips, I dwell in the midst of a people having unclean lips; and I have seen with my eyes the King, the Lord of hosts. ⁶ Then one of the seraphim was sent to me, and he had in his hand a coal which he had taken off the altar with the tongs; ⁷ and he touched my mouth and said, Behold, this has touched your lips, and will take away your iniquities, and will purge off your sins.
