5“Perform this sign,” the LORD told him. “Then they will believe that the LORD, the God of their ancestors—the God of Abraham, the God of Isaac, and the God of Jacob—really has appeared to you.”
6Then the LORD said to Moses, “Now put your hand inside your cloak.” So Moses put his hand inside his cloak, and when he took it out again, his hand was white as snow with a severe skin disease.
7“Now put your hand back into your cloak,” the LORD said. So Moses put his hand back in, and when he took it out again, it was as healthy as the rest of his body.
9And 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.”
10But 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.”
11Then 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?
14Then 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.
18So Moses went back home to Jethro, his father-in-law. “Please let me return to my relatives in Egypt,” Moses said. “I don’t even know if they are still alive.” “Go in peace,” Jethro replied.
21And the LORD told Moses, “When you arrive back in Egypt, go to Pharaoh and perform all the miracles I have empowered you to do. But I will harden his heart so he will refuse to let the people go.
25But Moses’ wife, Zipporah, took a flint knife and circumcised her son. She touched his feet with the foreskin and said, “Now you are a bridegroom of blood to me.”
28Moses then told Aaron everything the LORD had commanded him to say. And he told him about the miraculous signs the LORD had commanded him to perform.
31Then the people of Israel were convinced that the LORD had sent Moses and Aaron. When they heard that the LORD was concerned about them and had seen their misery, they bowed down and worshiped.
