5 The Egyptians shall know that I am the Lord, when I stretch out my hand on Egypt, and bring out the children of Israel from amongst them.”
6 Moses and Aaron did so. As the Lord commanded them, so they did.
7 Moses was eighty years old, and Aaron eighty-three years old, when they spoke to Pharaoh.
8 The Lord spoke to Moses and to Aaron, saying,
9 “When Pharaoh speaks to you, saying, ‘Perform a miracle!’ then you shall tell Aaron, ‘Take your rod, and cast it down before Pharaoh, that it become a serpent.’”
10 Moses and Aaron went in to Pharaoh, and they did so, as the Lord had commanded: and Aaron cast down his rod before Pharaoh and before his servants, and it became a serpent.
11 Then Pharaoh also called for the wise men and the sorcerers. They also, the magicians of Egypt, did the same thing with their enchantments.
