Isaiah 6:2-7 And seraphs 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.

LXX2012⁽ⁱ⁾ ² And seraphs 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 lintel 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 mine eyes the King, the Lord of hosts. ⁶ And there was sent to me one of the seraphs, 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.
