Exodus 5:1-2

CAB(i) 1 And after this Moses and Aaron went in to Pharaoh, and they said to him, Thus says the Lord God of Israel: Let My people go, that they may keep a feast to Me in the wilderness. 2 And Pharaoh said, Who is He that I should listen to His voice, so that I should send away the children of Israel? I do not know the Lord, and I will not let Israel go.
