Exodus 8:32 YLT

³⁰  And Moses goeth out from Pharaoh, and maketh supplication unto Jehovah,

³¹  and Jehovah doth according to the word of Moses, and turneth aside the beetle from Pharaoh, from his servants, and from his people -- there hath not been left one;

³²  and Pharaoh hardeneth his heart also at this time, and hath not sent the people away.
