Exodus 7:8-16

Now the LORD spoke to Moses and Aaron, saying, “When Pharaoh speaks to you, saying, ‘Work a miracle,’ then you shall say to Aaron, ‘Take your staff and throw it down before Pharaoh, that it may become a serpent.’ ” So Moses and Aaron came to Pharaoh, and thus they did just as the LORD had commanded; and Aaron threw his staff down before Pharaoh and his servants, and it became a serpent. Then Pharaoh also called for the wise men and the sorcerers, and they also, the magicians of Egypt, did the same with their secret arts. For each one threw down his staff and they turned into serpents. But Aaron’s staff swallowed up their staffs. Yet Pharaoh’s heart was hardened, and he did not listen to them, as the LORD had said. Then the LORD said to Moses, “Pharaoh’s heart is stubborn; he refuses to let the people go. Go to Pharaoh in the morning as he is going out to the water, and station yourself to meet him on the bank of the Nile; and you shall take in your hand the staff that was turned into a serpent. You shall say to him, ‘The LORD, the God of the Hebrews, sent me to you, saying, “Let My people go, that they may serve Me in the wilderness. But behold, you have not listened until now.”
