Exodus 8:29-31

Amplified Bible

²⁹ Moses said, “I am going to leave you, and I will urgently petition (pray, entreat) the Lord that the swarms of insects may leave Pharaoh, his servants, and his people tomorrow; only do not let Pharaoh act deceitfully again by not letting the people go to sacrifice to the Lord.”

³⁰ So Moses left Pharaoh and prayed to the Lord [on behalf of Pharaoh]. ³¹ The Lord did as Moses asked, and removed the swarms of [bloodsucking] insects from Pharaoh, from his servants and from his people; not one remained.
