Exodus 7:8-10

Amplified Bible

Aaron’s Rod Becomes a Serpent

⁸ Now the Lord said to Moses and Aaron, ⁹ “When Pharaoh says to you, ‘Work a miracle [to prove your authority],’ then you say to Aaron, ‘Take your staff and throw it down before Pharaoh, so that it may become a serpent.’” ¹⁰ So Moses and Aaron came to Pharaoh, and did just as the Lord had commanded; Aaron threw down his staff before Pharaoh and his servants, and it became a serpent.
