Isaiah 6:5-7 Lexham English Bible (LEB)
5 And I said, “Woe to me! For I am destroyed! For I am a man of unclean lips, and I am living among a people of unclean lips, for my eyes have seen the king, Yahweh of hosts!”
6 Then one of the seraphs flew to me, and in his hand was a hot coal he had taken from the altar with tongs.
7 And he touched my mouth, and he said,
“Look! This has touched your lips
and has removed your guilt,
and your sin is annulled.”
