Exodus 4:10-12

New Revised Standard Version, Anglicised

¹⁰ But Moses said to the Lord, ‘O my Lord, I have never been eloquent, neither in the past nor even now that you have spoken to your servant; but I am slow of speech and slow of tongue.’ ¹¹ Then the Lord said to him, ‘Who gives speech to mortals? Who makes them mute or deaf, seeing or blind? Is it not I, the Lord? ¹² Now go, and I will be with your mouth and teach you what you are to speak.’
