Exodus 5:1-2

New Century Version

Moses and Aaron Before the King

5 After Moses and Aaron talked to the people, they went to the king of Egypt and said, “This is what the Lord, the God of Israel, says: ‘Let my people go so they may hold a feast for me in the desert.’”

² But the king of Egypt said, “Who is the Lord? Why should I obey him and let Israel go? I do not know the Lord, and I will not let Israel go.”
