5“This is so that they may believe that the LORD, the God of their fathers—the God of Abraham, the God of Isaac, and the God of Jacob—has appeared to you.”
6Furthermore, the LORD said to Moses, “Put your hand inside your cloak.” So he put his hand inside his cloak, and when he took it out, his hand was leprous, white as snow.

9But if they do not believe even these two signs or listen to your voice, take some water from the Nile and pour it on the dry ground. Then the water you take from the Nile will become blood on the ground.”

18Then Moses went back to his father-in-law Jethro and said to him, “Please let me return to my brothers in Egypt to see if they are still alive.” “Go in peace,” Jethro replied.
21The LORD instructed Moses, “When you go back to Egypt, see that you perform before Pharaoh all the wonders that I have put within your power. But I will harden his heart so that he will not let the people go.
