Exodus 5:1-2

Amplified Bible, Classic Edition

5 Afterward Moses and Aaron went in and told Pharaoh, Thus says the Lord, the God of Israel, Let My people go, that they may hold a feast to Me in the wilderness.

² But Pharaoh said, Who is the Lord, that I should obey His voice to let Israel go? I know not the Lord, neither will I let Israel go.
