Exodus 8:29
Amplified Bible (AMP)
Moses said, I go out from you, and I will entreat the Lord that the swarms [of bloodsucking gadflies] may depart from Pharaoh, his servants, and his people tomorrow; only let not Pharaoh deal deceitfully any more in not letting the people go to sacrifice to the Lord.— Exodus 8:29 (AMP)
