Isaiah 6:6-13

Then flew one of the seraphim unto me, having a live coal in his hand, which he had taken with the tongs from off the altar: and he touched my mouth with it, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin forgiven. 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. And he said, Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but perceive not. 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 understand with their heart, and turn again, and be healed. Then said I, Lord, how long? And he answered, Until cities be waste without inhabitant, and houses without man, and the land become utterly waste, and Jehovah have removed men far away, and the forsaken places be many in the midst of the land. And if there be yet a tenth in it, it also shall in turn be eaten up: as a terebinth, and as an oak, whose stock remaineth, when they are felled; so the holy seed is the stock thereof.
