But Moses pleaded with the Lord, “O Lord, I’m not very goog with words. I never have been, and I’m now not, even though you have spoken to me, I get tongue-tid , and my words get tangled.”
The the Lord asked Moses, “Who make a person’s mouth? Who decides whether people speak or do not speak, hear or do not hear, see and not see? No go! I will be with you as you speak, and I will instruct you what to say.”
But Moses pleaded again,”Lord, please! Send someone else!”
Then the Lord became angry with Moses. “All right,” He said, “What about your brother, Aaron the Levite? I know he speaks well. And look! He is on his way to meet you now. He will be delighted to see you. Talk to him, and put the words in his mouth. I will be with both of you as you speak, and I will instruct both of you in what to do. Aaron will be your spokesman to the people. He will be your mouthpiece, and you will stand in the place of God for him, telling him what to say. And take you shepherd’s staff with you and use it to perform the miraculous signs I have shown you.” (vv. 10-17, NLT)
