International Standard Version
1In the year that King Uzziah died, I saw the Lord sitting upon his throne, high and exalted. The train of his robe filled the Temple. 2The seraphim stood above him. Each had six wings: with two he covered his face, and with two he covered his feet, and with two he was flying.
3They kept on calling to each other: "Holy, holy, holy is the LORD of the Heavenly Armies! The whole earth is full of his glory!"
4The foundations of the thresholds quaked at the sound of those who kept calling out, and the Temple was filled with smoke.
5"How terrible it will be for me!" I cried, "because I am ruined! I'm a man with unclean lips, and I live among a people with unclean lips! And my eyes have seen the King, the LORD of the Heavenly Armies!"
6Then one of the seraphim flew to me, carrying a burning coal in his hand that he had taken from the altar with tongs. 7He touched my mouth and said, "Look! Now that this has touched your lips, your guilt is taken away, and your sins atoned for."
8Then I heard the voice of the LORD as he was asking, "Whom will I send? Who will go for us?" "Here I am!" I replied. "Send me."
9"Go!" he responded. "Tell this people: "'Keep on hearing, but do not understand; keep on seeing, but do not perceive.'
10Dull the mind of this people, deafen their ears, and blind their eyes. By doing so, they won't see with their eyes, hear with their ears, understand with their minds, turn back, and be healed."
11Then I asked, "For how long, LORD?" He replied: "Until cities lie waste, without inhabitants, and houses without people; and the land becomes utterly desolate.
12Until the LORD removes people far away, and there are many empty places in the middle of the land.
13Even though a tenth of its people remain in it, it will once again be burned, like a terebinth or an oak tree, the stump of which, though the tree has been felled, still contains holy seed."
