But 1I will harden Pharaoh's heart, and though I 2multiply my signs and wonders in the land of Egypt,
Pharaoh will not listen to you. Then I will lay my hand on Egypt and bring my hosts, my people the children of Israel, out of the land of Egypt by great acts of judgment.
The Egyptians 3shall know that I am the LORD, when I stretch out my hand against Egypt and bring out the people of Israel from among them."
Moses and Aaron did so; they did just as the LORD commanded them.
Now Moses was 4eighty years old, and Aaron eighty-three years old, when they spoke to Pharaoh.
Then the LORD said to Moses and Aaron,
"When Pharaoh says to you, 5'Prove yourselves by working a miracle,' then you shall say to Aaron, 'Take your staff and cast it down before Pharaoh, that it may become a serpent.'"
So Moses and Aaron went to Pharaoh and did just as the LORD commanded. Aaron cast down his staff before Pharaoh and his servants, and it became a serpent.
Then Pharaoh summoned the wise men and the sorcerers, and they, the 6magicians of Egypt, also 7did the same by their secret arts.
For each man cast down his staff, and they became serpents. But Aaron's staff swallowed up their staffs.
Still 8Pharaoh's heart was hardened, and he would not listen to them, 9as the LORD had said.
