Moses answered before the Lord: Behold, the children of Israel do no hearken to me; and how will Pharao hear me, especially as I am of uncircumcised lips?
Moses said: I beseech thee, Lord, I am not eloquent from yesterday and the day before; and since thou hast spoken to thy servant, I have more impediment and slowness of tongue.
And I said: Woe is me, because I have held my peace; because I am a man of unclean lips, and I dwell in the midst of a people that hath unclean lips, and I have seen with my eyes the King the Lord of hosts.
