Above him were seraphim, each with six wings: With two wings they covered their faces, with two they covered their feet, and with two they were flying.
And they were calling to one another: “Holy, holy, holy is the LORD Almighty; the whole earth is full of his glory.”
At the sound of their voices the doorposts and thresholds shook and the temple was filled with smoke.
“Woe to me!” I cried. “I am ruined! For I am a man of unclean lips, and I live among a people of unclean lips, and my eyes have seen the King, the LORD Almighty.”
Then one of the seraphim flew to me with a live coal in his hand, which he had taken with tongs from the altar.
