1Then Moses answered, “What if they do not believe me or listen to my voice? For they may say, ‘The LORD has not appeared to you.’”
2And the LORD asked him, “What is that in your hand?” “A staff,” he replied.
3“Throw it on the ground,” said the LORD. So Moses threw it on the ground, and it became a snake, and he ran from it.
4“Stretch out your hand and grab it by the tail,” the LORD said to Moses, who reached out his hand and caught the snake, and it turned back into a staff in his hand.
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.
7“Put your hand back inside your cloak,” said the LORD. So Moses put his hand back inside his cloak, and when he took it out, it was restored, like the rest of his skin.
8And the LORD said, “If they refuse to believe you or heed the witness of the first sign, they may believe that of the second.
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.”
