Aaron’s Miraculous Rod

⁸ The Lord said to Moses and Aaron, ⁹ ‘When Pharaoh says to you, “Perform a wonder”, then you shall say to Aaron, “Take your staff and throw it down before Pharaoh, and it will become a snake.”’ ¹⁰ So Moses and Aaron went to Pharaoh and did as the Lord had commanded; Aaron threw down his staff before Pharaoh and his officials, and it became a snake.
