Exodus 5:1-2

Living Bible

5 After this presentation to the elders, Moses and Aaron went to see Pharaoh. They told him, “We bring you a message from Jehovah, the God of Israel. He says, ‘Let my people go, for they must make a holy pilgrimage out into the wilderness, for a religious feast, to worship me there.’”

² “Is that so?” retorted Pharaoh. “And who is Jehovah, that I should listen to him, and let Israel go? I don’t know Jehovah and I will not let Israel go.”
