Exodus 7:10 ASV

⁸  And Jehovah spake unto Moses and unto Aaron, saying,

⁹  When Pharaoh shall speak unto you, saying, Show a wonder for you; then thou shalt say unto Aaron, Take thy rod, and cast it down before Pharaoh, that it become a serpent.

¹⁰  And Moses and Aaron went in unto Pharaoh, and they did so, as Jehovah had commanded: and Aaron cast down his rod before Pharaoh and before his servants, and it became a serpent.

¹¹  Then Pharaoh also called for the wise men and the sorcerers: and they also, the magicians of Egypt, did in like manner with their enchantments.

¹²  For they cast down every man his rod, and they became serpents: but Aaron's rod swallowed up their rods.
