19And the LORD 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 an ass, and he returned to the land of Egypt: and Moses took the rod of God in his hand. 21And the LORD 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 the LORD, 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 the LORD 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.
