Exodus 7:11-13

Young's Literal Translation

¹¹ And Pharaoh also calleth for wise men, and for sorcerers; and the scribes of Egypt, they also, with their flashings, do so,

¹² and they cast down each his rod, and they become monsters, and the rod of Aaron swalloweth their rods;

¹³ and the heart of Pharaoh is strong, and he hath not hearkened unto them, as Jehovah hath spoken.
