Yeshayah 6:6-8

Orthodox Jewish Bible

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.
