Isaiah 6:3-5

And one cried unto another, and said, Holy, holy, holy, is Jehovah of hosts: the whole earth is full of his glory. And the foundations of the thresholds shook at the voice of him that cried, and the house was filled with smoke. Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, Jehovah of hosts.
