Exodus 8:23-25

New Catholic Bible

²³ We will go into the desert, a three days’ journey, and that is where we will sacrifice to the Lord, our God, just as he has ordered us.”

²⁴ So Pharaoh answered, “I will let you go and you can sacrifice to the Lord in the desert. Only do not go too far and pray for me.”

²⁵ Moses answered, “I will leave you and pray to the Lord. Tomorrow the flies will depart from Pharaoh, from his ministers, and from the people. Pharaoh, however, must not deceive us by not letting the people go to perform their sacrifice to the Lord.”
