2 Above Him stood ministering the [flaming] seraphim; each one had six wings: with two he covered his face, with two he covered his feet, and with two he did fly.
3 And one cried unto another, and said, Kadosh, Kadosh, Kadosh, is Hashem Tzva'os; kol ha'aretz is full of His kavod.
4 And the doorposts shook at the voice of him that cried, and the Beis [Hamikdash] was filled with smoke.
5 Then said I, Oy (Woe) is me! For I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for mine eyes have seen HaMelech, Hashem Tzva'os.
6 Then flew one of the seraphim unto me, having a live coal in his yad, which he had taken with the tongs from off the Mizbe'ach:
7 And he laid it upon my mouth, and said, Hinei, this hath touched thy lips; and thine avon (iniquity) is taken away, and kapporah is made for the purging of thy chattat (sin).
8 Also I heard the voice of Adonoi, saying, Whom shall I send, and who will go for Us? Then said I, Hineini; send me.
