4Pharaoh will not listen to you. I will reach into Egypt and bring out my regiments, my people the Israelites, from the land of Egypt with great acts of judgment.
5Then the Egyptians will know that I am the LORD, when I extend my hand over Egypt and bring the Israelites out from among them.
6And Moses and Aaron did so; they did just as the LORD commanded them.
7Now Moses 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,‘Do a miracle,’ and you say to Aaron,‘Take your staff and throw it down before Pharaoh,’ it will become a snake.”
10When Moses and Aaron went to Pharaoh, they did so, just as the LORD had commanded them– Aaron threw down his staff before Pharaoh and his servants and it became a snake.
