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.
11 Then Pharaoh also called the chachamim and the mechashefim: now the kharetumei Mitzrayim, they also did in like manner with their secret lore.
12 For they cast down every man his matteh, and they became serpents: but the matteh Aharon swallowed up their mattot.
13 And He hardened lev Pharaoh, that he paid heed not unto them; as Hashem had said.
14 And Hashem said unto Moshe, the lev Pharaoh is hardened, he refuseth to let the people go.
