Exodus 5:1-2

Wycliffe Bible

5 After these things Moses and Aaron entered, and said to Pharaoh, The Lord God of Israel saith these things, Deliver thou my people, that it make sacrifice to me in desert (The Lord God of Israel saith these things, Let my people go, so that they can hold a Feast unto me in the wilderness).

² And Pharaoh answered, Who is the Lord, that I hear his voice, and deliver Israel? I know not the Lord, and I shall not deliver Israel. (And Pharaoh answered, Who is the Lord, that I should listen to him, and let Israel go? I do not know the Lord, and I will not let Israel go.)
