The LORD said to Moses and Aaron,
"When Pharaoh says to you, 'Perform a miracle,3' then say to Aaron, 'Take your staff and throw it down before Pharaoh,' and it will become a snake."410
So Moses and Aaron went to Pharaoh and did just as the LORD commanded. Aaron threw his staff down in front of Pharaoh and his officials, and it became a snake.
Pharaoh then summoned wise men and sorcerers,5 and the Egyptian magicians6 also did the same things by their secret arts:712
Each one threw down his staff and it became a snake. But Aaron's staff swallowed up their staffs.
Yet Pharaoh's heart8 became hard and he would not listen9 to them, just as the LORD had said.
Then the LORD said to Moses, "Pharaoh's heart is unyielding;10 he refuses to let the people go.
Go to Pharaoh in the morning as he goes out to the water.11 Wait on the bank of the Nile12 to meet him, and take in your hand the staff that was changed into a snake.
Then say to him, 'The LORD, the God of the Hebrews, has sent me to say to you: Let my people go, so that they may worship13 me in the desert. But until now you have not listened.14
