Isaiah 6:6-13

Then one of the seraphim flew to me, having in his hand a live coal which he had taken with the tongs from the altar. And he touched my mouth with it, and said: “Behold, this has touched your lips; Your iniquity is taken away, And your sin purged.” Also 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: ‘Keep on hearing, but do not understand; Keep on seeing, but do not perceive.’ “Make the heart of this people dull, And their ears heavy, And shut their eyes; Lest they see with their eyes, And hear with their ears, And understand with their heart, And return and be healed.” Then I said, “Lord, how long?” And He answered: “Until the cities are laid waste and without inhabitant, The houses are without a man, The land is utterly desolate, The LORD has removed men far away, And the forsaken places are many in the midst of the land. But yet a tenth will be in it, And will return and be for consuming, As a terebinth tree or as an oak, Whose stump remains when it is cut down. So the holy seed shall be its stump.”
