Isaiah 6:1-7 New International Version - UK (NIVUK)
6 In the year that King Uzziah died, I saw the Lord, high and exalted, seated on a throne; and the train of his robe filled the temple. 2 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. 3 And they were calling to one another:
‘Holy, holy, holy is the Lord Almighty;
4 At the sound of their voices the doorposts and thresholds shook and the temple was filled with smoke.
5 ‘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.’
6 Then one of the seraphim flew to me with a live coal in his hand, which he had taken with tongs from the altar. 7 With it he touched my mouth and said, ‘See, this has touched your lips; your guilt is taken away and your sin atoned for.’
