4But Pharaoh will not listen to you, and I will lay my hand on Egypt, and bring forth my hosts, my people the children of Israel, out of the land of Egypt by great judgments.
5The Egyptians shall know that I am Yahweh, when I stretch forth my hand on Egypt, and bring out the children of Israel from among them."
6Moses and Aaron did so. As Yahweh commanded them, so they did.
7Moses was eighty years old, and Aaron eighty-three years old, when they spoke to Pharaoh.
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.`"
10Moses and Aaron went in to Pharaoh, and they did so, as Yahweh had commanded: and Aaron cast down his rod before Pharaoh and before his servants, and it became a serpent.
