Exodus 3:4-14; 4:13-16
4 When the Lord saw that he had gone over to look, God called to him from within the bush, “Moses! Moses!”
And Moses said, “Here I am.”
5 “Do not come any closer,” God said. “Take off your sandals, for the place where you are standing is holy ground.” 6 Then he said, “I am the God of your father, the God of Abraham, the God of Isaac and the God of Jacob.” At this, Moses hid his face, because he was afraid to look at God.
7 The Lord said, “I have indeed seen the misery of my people in Egypt. I have heard them crying out because of their slave drivers, and I am concerned about their suffering. 8 So I have come down to rescue them from the hand of the Egyptians and to bring them up out of that land into a good and spacious land, a land flowing with milk and honey—the home of the Canaanites, Hittites, Amorites, Perizzites, Hivites and Jebusites. 9 And now the cry of the Israelites has reached me, and I have seen the way the Egyptians are oppressing them. 10 So now, go. I am sending you to Pharaoh to bring my people the Israelites out of Egypt.”
11 But Moses said to God, “Who am I that I should go to Pharaoh and bring the Israelites out of Egypt?”
12 And God said, “I will be with you. And this will be the sign to you that it is I who have sent you: When you have brought the people out of Egypt, you will worship God on this mountain.”
13 Moses said to God, “Suppose I go to the Israelites and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ Then what shall I tell them?”
14 God said to Moses, “I am who I am. This is what you are to say to the Israelites: ‘I am has sent me to you.’”
Exodus 4:13-16 But Moses said, “Pardon your servant, Lord. Please send someone else.” 14 Then the Lord’s anger burned against Moses and he said, “What about your brother, Aaron the Levite? I know he can speak well. He is already on his way to meet you, and he will be glad to see you. 15 You shall speak to him and put words in his mouth; I will help both of you speak and will teach you what to do. 16 He will speak to the people for you, and it will be as if he were your mouth and as if you were God to him.
Exodus 4:10-12 Moses said to the Lord, “Pardon your servant, Lord. I have never been eloquent, neither in the past nor since you have spoken to your servant. I am slow of speech and tongue.” 11 The Lord said to him, “Who gave human beings their mouths? Who makes them deaf or mute? Who gives them sight or makes them blind? Is it not I, the Lord? 12 Now go; I will help you speak and will teach you what to say.”
Acts 7:20-22 “At that time Moses was born, and he was no ordinary child. For three months he was cared for by his family. 21 When he was placed outside, Pharaoh’s daughter took him and brought him up as her own son. 22 Moses was educated in all the wisdom of the Egyptians and was powerful in speech and action.
