Charles Spurgeon Commentary Isaiah 6:5

"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." — Isaiah 6:5 (ASV)

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, the LORD of hosts.

There was, indeed, enough to make him say, Woe is me! A sinful preacher, an imperfect preacher, among a sinful and imperfect people, he felt as if the society in which he moved was the reverse of the society in which God dwells. Pure seraphim cry, Holy, holy, holy, is the Lord of hosts; but as for us, our very talk is unholy: a people of unclean lips.
