Exodus 7:9-11

Amplified Bible

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. ¹¹ Then Pharaoh called for the wise men [skilled in magic and omens] and the sorcerers [skilled in witchcraft], and they also, these magicians (soothsayer-priests) of Egypt, did the same with their secret arts and enchantments.
