Exodus 5:1-2

1After this, Moses and Aaron went to visit Pharaoh. They said to him, ‘Listen to what the Lord says. He is the God of Israel. He says, “Let my people go. Let them prepare a feast in the desert to worship me.” ’

2But Pharaoh said, ‘The Lord is not my god. I do not need to obey him. I do not have to let the Israelites go. I do not know the Lord. I will not let the Israelites go.’
