Exodus 4:8-17

The LORD said to Moses, “If they do not believe you and are not convinced by the first miraculous sign, they will be convinced by the second sign. And if they don’t believe you or listen to you even after these two signs, then take some water from the Nile River and pour it out on the dry ground. When you do, the water from the Nile will turn to blood on the ground.” But Moses pleaded with the LORD, “O Lord, I’m not very good with words. I never have been, and I’m not now, even though you have spoken to me. I get tongue-tied, and my words get tangled.” Then the LORD asked Moses, “Who makes a person’s mouth? Who decides whether people speak or do not speak, hear or do not hear, see or do not see? Is it not I, the LORD? Now go! I will be with you as you speak, and I will instruct you in what to say.” But Moses again pleaded, “Lord, please! Send anyone 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 you both 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 your shepherd’s staff with you, and use it to perform the miraculous signs I have shown you.”
