Exodus 8:30-32

New Revised Standard Version Catholic Edition

³⁰ So Moses went out from Pharaoh and prayed to the Lord. ³¹ And the Lord did as Moses asked: he removed the swarms of flies from Pharaoh, from his officials, and from his people; not one remained. ³² But Pharaoh hardened his heart this time also, and would not let the people go.
