Exodus 8:22-24

Darby Translation

²² And I will distinguish in that day the land of Goshen, in which my people dwell, that no dog-flies shall be there; that thou mayest know that I Jehovah am in the midst of the land.

²³ And I will put a separation between my people and thy people; to-morrow shall this sign be.

²⁴ And Jehovah did so; and there came dog-flies in a multitude into the house of Pharaoh, and [into] the houses of his bondmen; and throughout the land of Egypt, the land was corrupted by the dog-flies.
