29 “Your Majesty,” Moses replied, “I'll pray for you as soon as I leave, and by tomorrow the flies will stop bothering you, your officials, and the citizens of your country. Only make sure that you're telling the truth this time and that you really intend to let our people offer sacrifices to the Lord.”
30 After leaving the palace, Moses prayed,
31 and the Lord answered his prayer. Not a fly was left to pester the king, his officials, or anyone else in Egypt.
32 But the king turned stubborn again and would not let the people go.
