Exodus 8:23-25

New Century Version

²³ I will treat my people differently from your people. This miracle will happen tomorrow.’”

²⁴ So the Lord did as he had said, and great swarms of flies came into the king’s palace and his officers’ houses. All over Egypt flies were ruining the land. ²⁵ The king called for Moses and Aaron and told them, “Offer sacrifices to your God here in this country.”
