[2] Above 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. [3] And one cried unto another, and said, Holy, is the LORD of hosts: the whole earth is full of his glory. [4] And the posts of the door moved 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, the LORD of hosts. [6] Then flew one of the seraphims unto me, having a live coal in his hand, which he had taken with the tongs from off the altar: [7] And he laid it upon my mouth, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin purged.
