Exodus 7:11-16
English Standard Version
Chapter 7
11Then Pharaoh summoned the wise men and the sorcerers, and they, the magicians of Egypt, also did the same by their secret arts. 12For each man cast down his staff, and they became serpents. But Aaron 's staff swallowed up their staffs. 13Still Pharaoh 's heart was hardened, and he would not listen to them, as the Lord had said.
14Then the Lord said to Moses, "Pharaoh 's heart is hardened; he refuses to let the people go.
15Go to Pharaoh in the morning, as he is going out to the water, and stand on the bank of the Nile to meet him. Take in your hand the staff that turned into a serpent.
16And 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 so far, you have not obeyed.
