Go in, speak unto Pharaoh king of Egypt, that he let the children of Israel go out of his land.
Come now therefore, and I will send thee unto Pharaoh, that thou mayest bring forth my people the children of Israel out of Egypt.
And thou shalt say unto Pharaoh, Thus saith Yahweh, Israel is my son, even my firstborn:
And I say unto thee, Let my son go, that he may serve me: and if thou refuse to let him go, behold, I will slay thy son, even thy firstborn.
And afterward Moses and Aaron went in, and told Pharaoh, Thus saith Yahweh Elohim of Israel, Let my people go, that they may hold a feast unto me in the wilderness.
For since I came to Pharaoh to speak in thy name, he hath done evil to this people; neither hast thou delivered thy people at all.
And Yahweh spake unto Moses, saying,
That Yahweh spake unto Moses, saying, I am Yahweh: speak thou unto Pharaoh king of Egypt all that I say unto thee.
And Yahweh said unto Moses, See, I have made thee as Elohim to Pharaoh: and Aaron thy brother shall be thy prophet.
