Exodus 4:10

6The LORD said furthermore to him, “Now put your hand inside your cloak.” He put his hand inside his cloak, and when he took it out, behold, his hand was leprous, as white as snow.

7He said, “Put your hand inside your cloak again.” He put his hand inside his cloak again, and when he took it out of his cloak, behold, it had turned again as his other flesh.

8“It will happen, if they will not believe you or listen to the voice of the first sign, that they will believe the voice of the latter sign.

9It will happen, if they will not believe even these two signs or listen to your voice, that you shall take of the water of the river, and pour it on the dry land. The water which you take out of the river will become blood on the dry land.”

10Moses said to the LORD, “O Lord, I am not eloquent, neither before now, nor since you have spoken to your servant; for I am slow of speech, and of a slow tongue.”

11The LORD said to him, “Who made man’s mouth? Or who makes one mute, or deaf, or seeing, or blind? Isn’t it I, the LORD?

12Now therefore go, and I will be with your mouth, and teach you what you shall speak.”

13Moses said, “Oh, Lord, please send someone else.”

14The LORD’s anger burned against Moses, and he said, “What about Aaron, your brother, the Levite? I know that he can speak well. Also, behold, he is coming out to meet you. When he sees you, he will be glad in his heart.
