5 Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the middle of a people of unclean lips: for my eyes have seen the King, the LORD of hosts.

6 Then flew one of the seraphim to me, having a live coal in his hand, which he had taken with the tongs from off the altar:

7 And he laid it on my mouth, and said, See, this has touched your lips; and your iniquity is taken away, and your sin purged.
