Isaías 6:8+ - Bíblia Online

In the year that king Uzziah died I then saw the Lord sitting on a throne, high and lifted up, and His train filled the temple. 
Above it stood the seraphs; each one had six wings; with two he covered his face, and with two he covered his feet, and with two he flew. 
And one cried to another, and said, Holy, holy, holy, [is] the LORD of hosts; the whole earth full of His glory. 
And the doorposts moved at the voice of the one who cried, and the house was filled with smoke. 
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. 
Then one of the seraphs flew to me, having a live coal in his hand, snatched with tongs from the altar. 
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. 
And I heard the voice of the Lord, saying, whom shall I send, and who will go for us? Then I said, Here [am] I; send me! 
And He said, Go, and tell this people, You hear indeed, but do not understand; and seeing you see, but do not know. 
Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their hearts, and turn back, and be healed. 
Then I said, Lord, how long? And He answered, Until the cities are wasted without inhabitant, and the houses without man, and the land laid waste, a desolation, 
and [until] the LORD has moved men far away, and the desolation in the midst of the land [is] great. 
But yet in it [shall be] a tenth, and [it] shall return and be consumed like the terebinth and like the oak being felled, [yet has] its stump; the holy seed [is] its stump.
