Exodus 5:1-4

And afterward Moses and Aaron came and said to Pharaoh, “Thus says the LORD, the God of Israel, ‘Let My people go that they may celebrate a feast to Me in the wilderness.’ ” But Pharaoh said, “Who is the LORD that I should obey His voice to let Israel go? I do not know the LORD, and besides, I will not let Israel go.” Then they said, “The God of the Hebrews has met with us. Please, let us go a three days’ journey into the wilderness that we may sacrifice to the LORD our God, otherwise He will fall upon us with pestilence or with the sword.” But the king of Egypt said to them, “Moses and Aaron, why do you draw the people away from their work? Get back to your labors!”
