³⁷ But though he had done so many signs before them, yet they believed not on him: ³⁸ that the word of Isaiah the prophet might be fulfilled, which he spake,

³⁹ For this cause they could not believe, for that Isaiah said again,

⁴¹ These things said Isaiah, because he saw his glory; and he spake of him.

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.
