Yeshayah 6:5-7 Orthodox Jewish Bible (OJB)
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).
