Exodus 7:8 YLT

⁶  And Moses doth -- Aaron also -- as Jehovah commanded them; so have they done;

⁷  and Moses 'is' a son of eighty years, and Aaron 'is' a son of eighty and three years, in their speaking unto Pharaoh.

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

⁹  'When Pharaoh speaketh unto you, saying, Give for yourselves a wonder; then thou hast said unto Aaron, Take thy rod, and cast before Pharaoh -- it becometh a monster.'

¹⁰  And Moses goeth in -- Aaron also -- unto Pharaoh, and they do so as Jehovah hath commanded; and Aaron casteth his rod before Pharaoh, and before his servants, and it becometh a monster.
