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.
