Exodus 5:1-4

Afterward Moses and Aaron went to Pharaoh and said, “This is what the LORD, the God of Israel, says: ‘Let my people go, so that they may hold a festival to me in the wilderness.’ ” Pharaoh said, “Who is the LORD, that I should obey him and let Israel go? I do not know the LORD and I will not let Israel go.” Then they said, “The God of the Hebrews has met with us. Now let us take a three-day journey into the wilderness to offer sacrifices to the LORD our God, or he may strike us with plagues or with the sword.” But the king of Egypt said, “Moses and Aaron, why are you taking the people away from their labor? Get back to your work!”
