Acts 7:22; Exodus 4:10; Exodus 4:14-16; Exodus 6:12; Exodus 6:30

22 And Moses was instructed in all the wisdom of the Egyptians, and he was mighty in his words and deeds.

10 But Moses said to the LORD, "Oh, my Lord, I am not eloquent, either in the past or since you have spoken to your servant, but I am slow of speech and of tongue."

14 Then the anger of the LORD was kindled against Moses and he said, "Is there not Aaron, your brother, the Levite? I know that he can speak well. Behold, he is coming out to meet you, and when he sees you, he will be glad in his heart.

15 You shall speak to him and put the words in his mouth, and I will be with your mouth and with his mouth and will teach you both what to do.

16 He shall speak for you to the people, and he shall be your mouth, and you shall be as God to him.

12 But Moses said to the LORD, "Behold, the people of Israel have not listened to me. How then shall Pharaoh listen to me, for I am of uncircumcised lips?"

30 But Moses said to the LORD, "Behold, I am of uncircumcised lips. How will Pharaoh listen to me?"
