Moses said furthermore: "I am not an eloquent man, nor can I see of what avail words can be in this matter. Thou art sending me to one that is himself a slave, to Pharaoh of the tribe of Ham, and a slave will not be corrected by words. I consent to go on Thy errand only if Thou wilt invest me with the power of chastising Pharaoh with brute force." To these words spoken by Moses, God made reply: "Let it not fret thee that thou art not an eloquent speaker.
It is I that made the mouth of all that speak, and I that made men dumb. One I make to see, another I make blind; one I make to hear, another I make deaf. Had I willed it so, thou hadst been a man of ready speech. But I desired to show a wonder through thee.
Whenever I will it, the words I cast into thy mouth shall come forth without hesitation. But what thou sayest about a slave, that he cannot be corrected by words, is true, and therefore I give thee My rod for Pharaoh's castigation."
