Exodus 8:25-29

25Pharaoh called for Moses and Aaron and said, “Go, sacrifice to your God here in this country.”

26Moses replied, “It wouldn’t be right to do that. The sacrifices we offer to the Lord our God are disgusting to Egyptians. If they see us offer sacrifices that they consider disgusting, won’t they stone us to death?

27We need to travel three days into the desert to offer sacrifices to the Lord our God, as he told us to do.”

28Pharaoh said, “I will let you go, but don’t go very far. You may offer sacrifices to the Lord your God in the desert and pray for me.”

29Moses answered, “As soon as I leave you, I will pray to the Lord. Tomorrow the swarms of flies will go away from you, your officials, and your people. But you must stop tricking us by not letting the people go to offer sacrifices to the Lord.”
