Exodus 4:6-9

GOD then said, “Put your hand inside your shirt.” He slipped his hand under his shirt, then took it out. His hand had turned leprous, like snow. He said, “Put your hand back under your shirt.” He did it, then took it back out—as healthy as before. “So if they don’t trust you and aren’t convinced by the first sign, the second sign should do it. But if it doesn’t, if even after these two signs they don’t trust you and listen to your message, take some water out of the Nile and pour it out on the dry land; the Nile water that you pour out will turn to blood when it hits the ground.”
