Exodus 8:27-30 Catholic Public Domain Version (CPDV)

27. We will sojourn three days' journey into the wilderness. And we will sacrifice to the Lord our God, just as he has instructed us."

28. And Pharaoh said: "I will release you in order to sacrifice to the Lord your God in the desert. Yet you may only go so far. Petition for me."

29. And Moses said: "After departing from you, I will pray to the Lord. And the flies will withdraw from Pharaoh, and from his servants, and from his people, tomorrow. Yet do not be willing to deceive any longer, so that you would not release the people to sacrifice to the Lord."

30. And Moses, departing from Pharaoh, prayed to the Lord.
