Isaiah 6:3 KJV

1In the year that king Uzziah died I saw also the LORD sitting upon a throne, high and lifted up, and his train filled the temple.

2Above it stood the seraphims: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly.

3And one cried unto another, and said, Holy, holy, holy, is the LORD of hosts: the whole earth is full of his glory.

4And the posts of the door moved at the voice of him that cried, and the house was filled with smoke.

5Then 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.
