So Moses and Aaron went to Pharaoh and obeyed the Lord. Aaron threw his walking stick down. While Pharaoh and his officers watched, the stick became a snake.
He is the enemy, but know that I have given you more power than he has. I have given you power to crush his snakes and scorpions under your feet. Nothing will hurt you.
If they hide at the top of Mount Carmel, I will find them there and take them from that place. If they try to hide from me at the bottom of the sea, I will command the snake, and it will bite them.
“Pharaoh will ask you to prove your power. He will ask you to do a miracle. Tell Aaron to throw his walking stick on the ground. While Pharaoh is watching, the stick will become a snake.”
So Moses and Aaron did what the Lord commanded. Aaron raised the walking stick and hit the water in the Nile River. He did this in front of Pharaoh and his officials. So all the water in the river changed into blood.
