Exodus 7:8-13 - Aaron's Staff Becomes A Snake

⁸ The Lord said to Moses and Aaron, ⁹ "When Pharaoh says to you, 'Do a miracle,' and you say to Aaron, 'Take your staff and throw it down before Pharaoh,' it will become a snake." ¹⁰ When Moses and Aaron went to Pharaoh, they did so, just as the Lord had commanded them -- Aaron threw down his staff before Pharaoh and his servants and it became a snake. ¹¹ Then Pharaoh also summoned wise men and sorcerers, and the magicians of Egypt by their secret arts did the same thing. ¹² Each man threw down his staff, and the staffs became snakes. But Aaron's staff swallowed up their staffs. ¹³ Yet Pharaoh's heart became hard, and he did not listen to them, just as the Lord had predicted.
