Isaiah 6:2-5

ASV(i) 2 Above him stood the seraphim: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly. 3 And one cried unto another, and said, Holy, holy, holy, is Jehovah of hosts: the whole earth is full of his glory. 4 And the foundations of the thresholds shook at the voice of him that cried, and the house was filled with smoke. 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.
