Exodus 8:28-30

Amplified Bible, Classic Edition

²⁸ So Pharaoh said, I will let you go, that you may sacrifice to the Lord your God in the wilderness; only you shall not go very far away. Entreat [your God] for me.

²⁹ 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.

³⁰ So Moses went out from Pharaoh and entreated the Lord.
