Exodus 8:23-25

New International Version

²³ I will make a distinction^[a] between my people and your people.^(A) This sign will occur tomorrow.’”

²⁴ And the Lord did this. Dense swarms of flies poured into Pharaoh’s palace and into the houses of his officials; throughout Egypt the land was ruined by the flies.^(B)

²⁵ Then Pharaoh summoned^(C) Moses and Aaron and said, “Go, sacrifice to your God here in the land.”
