And the Lord spake unto Moses and unto Aaron After he had given them their commission, and instructions to go to Pharaoh, and a little before they went in to him:
9
"If the king demands that you prove yourselves by performing a miracle, tell Aaron to take his walking stick and throw it down in front of the king, and it will turn into a snake."
10
So Moses and Aaron went to the king and did as the Lord had commanded. Aaron threw his walking stick down in front of the king and his officers, and it turned into a snake.
