Exodus 8:27-29

Revised Standard Version Catholic Edition

²⁷ We must go three days’ journey into the wilderness and sacrifice to the Lord our God as he will command us.” ²⁸ So Pharaoh said, “I will let you go, to sacrifice to the Lord your God in the wilderness; only you shall not go very far away. Make entreaty for me.” ²⁹ Then Moses said, “Behold, I am going out from you and I will pray to the Lord that the swarms of flies may depart from Pharaoh, from his servants, and from his people, tomorrow; only let not Pharaoh deal falsely again by not letting the people go to sacrifice to the Lord.”
