3 Yet I will harden Pharaoh’s heart, and multiply My signs and wonders in the land of Egypt.
4 But Pharaoh will not listen to you, so I will lay My hand upon Egypt, and bring forth My armies, My people Bnei-Yisrael, out of the land of Egypt by great judgments.
5 The Egyptians will know that I am Adonai, when I stretch out My hand against Egypt, and bring out Bnei-Yisrael from among them.”
6 So Moses and Aaron did as Adonai commanded them.
7 Moses was eighty years old and Aaron eighty-three years old when they spoke to Pharaoh.
8 Adonai told Moses and Aaron,
9 “When Pharaoh speaks to you saying, ‘Prove yourselves with a miracle,’ then you are to say to Aaron, ‘Take your staff and cast it down before Pharaoh, so that it may become a serpent.’”
