Exodus 4:18-28

18And Moses went and returned to Jethro his father in law, and said unto him, Let me go, I pray thee, and return unto my brethren which are in Egypt, and see whether they be yet alive. And Jethro said to Moses, Go in peace.1 19And Yhwh said unto Moses in Midian, Go, return into Egypt: for all the men are dead which sought thy life. 20And Moses took his wife and his sons, and set them upon a donkey, and he returned to the land of Egypt: and Moses took the rod of God in his hand. 21And Yhwh said unto Moses, When thou goest to return into Egypt, see that thou do all those wonders before Pharaoh, which I have put in thine hand: but I will harden his heart, that he shall not let the people go. 22And thou shalt say unto Pharaoh, Thus saith Yhwh, Israel is my son, even my firstborn: 23And 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.

24And it came to pass by the way in the inn, that Yhwh met him, and sought to kill him. 25Then Zipporah took a sharp stone, and cut off the foreskin of her son, and cast it at his feet, and said, Surely a bloody husband art thou to me.23 26So he let him go: then she said, A bloody husband thou art, because of the circumcision.

27And Yhwh said to Aaron, Go into the wilderness to meet Moses. And he went, and met him in the mount of God, and kissed him. 28And Moses told Aaron all the words of Yhwh who had sent him, and all the signs which he had commanded him.
