Exodus 4:2-9

2Then the LORD said to him, “What is that in your hand?” “A staff,” he replied.

3The LORD said, “Throw it on the ground.” Moses threw it on the ground and it became a snake, and he ran from it. 4Then the LORD said to him, “Reach out your hand and take it by the tail.” So Moses reached out and took hold of the snake and it turned back into a staff in his hand.

5“This,” said the LORD, “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.”

6Then the LORD said, “Put your hand inside your cloak.” So Moses put his hand into his cloak, and when he took it out, the skin was leprous The Hebrew word for leprous was used for various diseases affecting the skin. —it had become as white as snow.

7“Now put it back into your cloak,” he said. So Moses put his hand back into his cloak, and when he took it out, it was restored, like the rest of his flesh. 8Then the LORD said, “If they do not believe you or pay attention to the first sign, they may believe the second.

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