8 The LORD spoke to Moshe and to Aharon, saying,
9 "When Par`oh speaks to you, saying, 'Perform a miracle!' then you shall tell Aharon, 'Take your rod, and cast it down before Par`oh, that it become a serpent.'"
10 Moshe and Aharon went in to Par`oh, and they did so, as the LORD had commanded: and Aharon cast down his rod before Par`oh and before his servants, and it became a serpent.
11 Then Par`oh also called for the wise men and the sorcerers. They also, the magicians of Mitzrayim, did in like manner with their enchantments.
12 For they cast down every man his rod, and they became serpents: but Aharon's rod swallowed up their rods.
13 Par`oh's heart was hardened, and he didn't listen to them; as the LORD had spoken.
