25 Then the king sent for Moses and Aaron and told them, “Go and sacrifice to your God, but stay here in Egypt.”
26 “That's impossible!” Moses replied. “Any sacrifices we offer to the Lord our God would disgust the Egyptians, and they would stone us to death.
27 No indeed! The Lord has ordered us to walk three days into the desert before offering sacrifices to him, and that's what we have to do.”
28 Then the king told him, “I'll let you go into the desert to offer sacrifices, if you don't go very far. But in the meantime, pray for me.”
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.
