Using biblegateway.com which is excellent for searching for pasages in the bible, I have found the verse is Isiah 6 v5.

King James Version gives:

"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."

The New International Version gives:

"Woe to me!" I cried. "I am ruined! For I am a man of unclean lips, and I live among a people of unclean lips, and my eyes have seen the King, the LORD Almighty."

So "ruined" would again seem a fair bet.

I have also tried Young's Literal Translation which I believe sticks closer to the original Hebrew. It uses neither term though...

"And I say, `Wo to me, for I have been silent, For a man -- unclean of lips [am] I, And in midst of a people unclean of lips I am dwelling, Because the King, Jehovah of Hosts, have my eyes seen.'"
