3. And I will harden the lev Pharaoh, and multiply My Otot and My Mofetim in Eretz Mitzrayim.
4. But Pharaoh shall not pay heed unto you, that I may lay My yad upon Mitzrayim, and bring forth Mine tzve'os, and My people the Bnei Yisroel, out of Eretz Mitzrayim by shefatim gedolim (great judgments).
5. And the Egyptians shall know that I am Hashem, when I stretch forth My yad upon Mitzrayim, bringing out Bnei Yisroel from among them.
6. And Moshe and Aharon did as Hashem commanded them, so did they.
7. And Moshe was fourscore years old, and Aharon fourscore three years, when they spoke unto Pharaoh.
8. And Hashem spoke unto Moshe and Aharon, saying,
9. When Pharaoh shall speak unto you, saying, Show a mofet (miracle) for you: then thou shalt say unto Aharon, Take thy matteh, and cast it before Pharaoh, and it shall become a serpent.
10. And Moshe and Aharon went in unto Pharaoh, and they did so as Hashem had commanded: and Aharon cast down his matteh before Pharaoh, and his avadim, and it became a serpent.
