MKJV(i)
5 Then I said, Woe is me! For I am undone; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, Jehovah of Hosts.
6 Then one of the seraphs flew to me, having a live coal in his hand, snatched with tongs from the altar.
7 And he laid it on my mouth and said, Lo, this has touched your lips; and your iniquity is taken away, and your sin purged.
