6 Next, the Lord commanded Moses, “Put your hand inside your shirt.” Moses obeyed, and when he took it out, his hand had turned white as snow—like someone with leprosy.
7 “Put your hand back inside your shirt,” the Lord told him. Moses did so, and when he took it out again, it was as healthy as the rest of his body.
8-9 Then the Lord said, “If no one believes either of these miracles, take some water from the River Nile and pour it on the ground. The water will immediately turn into blood.”
10 Moses replied, “I have never been a good speaker. I wasn't one before you spoke to me, and I'm not one now. I am slow at speaking, and I can never think of what to say.”
11 But the Lord answered, “Who makes people able to speak or makes them deaf or unable to speak? Who gives them sight or makes them blind? Don't you know that I am the one who does these things?
12 Now go! When you speak, I will be with you and give you the words to say.”
13 Moses begged, “Lord, please send someone else to do it.”
