Exodus 7:12 DBY

¹⁰  And Moses and Aaron went in to Pharaoh, and did so, as Jehovah had commanded; and Aaron cast down his staff before Pharaoh, and before his bondmen, and it became a serpent.

¹¹  And Pharaoh also called the sages and the sorcerers; and they too, the scribes of Egypt, did so with their enchantments:

¹²  they cast down every man his staff, and they became serpents; but Aaron's staff swallowed up their staves.

¹³  And Pharaoh's heart was stubborn, and he hearkened not to them, as Jehovah had said.

¹⁴  And Jehovah said to Moses, Pharaoh's heart is hardened: he refuseth to let the people go.
