Isaiah 6:1-10American Standard Version (ASV)
6 In the year that king Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and his [a]train filled the temple. 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: [b]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.
6 Then flew one of the seraphim unto me, having a [c]live coal in his hand, which he had taken with the tongs from off the altar: 7 and he touched my mouth with it, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin [d]forgiven. 8 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. 9 And he said, Go, and tell this people, Hear ye [e]indeed, but understand not; and see ye [f]indeed, but perceive not. 10 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 [g]understand with their heart, and turn again, and be healed.
