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.
15 Get thee unto Pharaoh in the boker; hinei, he goeth out unto the mayim; and thou shalt stand by the bank of the Nile to meet him; and the matteh which was turned to a nachash shalt thou take in thine yad.
16 And thou shalt say unto him, Hashem Elohei HaIvrim hath sent me unto thee, saying, Let My people go, that they may serve Me in the midbar: and, hinei, hitherto thou wouldest not hear.
17 Thus saith Hashem, In this thou shalt know that I am Hashem: hinei, I will strike with the matteh that is in Mine yad upon the mayim which are in the Nile, and they shall be turned to dahm.
