4Pharaoh will not listen to you, so I will stretch out my hand against Egypt and bring my armies—my people, the Israelites—out of the land of Egypt with great acts of judgment.
5The Egyptians will know that I am the Lord when I stretch out my hand against Egypt and bring the Israelites out from among them.
6Moses and Aaron did just as the Lord commanded them.
7Moses was eighty years old, and Aaron was eighty-three years old when they spoke to Pharaoh.
8The Lord said to Moses and Aaron,
9"When Pharaoh says to you, 'Perform a miracle,' you shall say to Aaron, 'Take your staff and throw it down before Pharaoh, and it will become a serpent.'"
10So Moses and Aaron went to Pharaoh and did just as the Lord had commanded. Aaron threw down his staff before Pharaoh and his officials, and it became a serpent.
