8 “If they do not believe you or pay attention to the former sign, then they may believe the latter sign. 9 And if they do not believe even these two signs or listen to you, then take some water from the Nile and pour it out on the dry ground. The water you take out of the Nile will become blood on the dry ground.” 10 Then Moses said to the Lord, “O my Lord, I am not an eloquent man, neither in the past nor since you have spoken to your servant, for I am slow of speech and slow of tongue.” 11 The Lord said to him, “Who gave a mouth to man, or who makes a person mute or deaf or seeing or blind? Is it not I, the Lord? 12 So now go, and I will be with your mouth and will teach you what you must say.”

4 The Lord’s message came to me, 5 “Before I formed you in your mother’s womb, I chose you. Before you were born, I set you apart.I appointed you to be a prophet to the nations.” 6 I answered, “Oh, Sovereign Lord, Really I do not know how to speak well enough for that, for I am too young.” 7 The Lord said to me, “Do not say, ‘I am too young.’ But go to whomever I send you and say whatever I tell you. 8 Do not be afraid of those to whom I send you, for I will be with you to protect you,” says the Lord.
