3 But I shall harden his heart, and shall multiply my signs and wonders in the land of Egypt,
4 And he will not hear you: and I will lay my hand upon Egypt, and will bring forth my army and my people the children of Israel out of the land of Egypt, by very great judgments.
5 And the Egyptians shall know that I am the Lord, who have stretched forth my hand upon Egypt, and have brought forth the children of Israel out of the midst of them.
6 And Moses and Aaron did as the Lord had commanded: so did they.
7 And Moses was eighty years old, and Aaron eighty-three, when they spoke to Pharao.
8 And the Lord said to Moses and Aaron:
9 When Pharao shall say to you, Shew signs: thou shalt say to Aaron: Take thy rod, and cast it down before Pharao, and it shall be turned into a serpent.
