And Moses said unto God, Who am I, that I should go unto Pharaoh, and that I should bring forth the children of Israel out of Egypt?
And Moses said unto Jehovah, Oh, Lord, I am not eloquent, neither heretofore, nor since thou hast spoken unto thy servant; for I am slow of speech, and of a slow tongue.
And now, O Jehovah my God, thou hast made thy servant king instead of David my father: and I am but a little child; I know not how to go out or come in.
Then said I, 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 the King, Jehovah of hosts.
Then flew one of the seraphim unto me, having a live coal in his hand, which he had taken with the tongs from off the altar:
and he touched my mouth with it, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin forgiven.
And I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then I said, Here am I; send me.
