[21] And the LORD said unto Moses, 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. [22] And thou shalt say unto Pharaoh, Thus saith the LORD, Israel is my son, even my firstborn: [23] 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. [24] And it came to pass by the way in the inn, that the LORD met him, and sought to kill [25] Then 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. [26] So he let him go: then she said, A bloody husband thou art, because of the circumcision. [27] And the LORD said to Aaron, into the wilderness to meet Moses. and met him in the mount of God, and kissed him. [28] And Moses told Aaron all the words of the LORD who had sent him, and all the signs which he had commanded [29] And Moses and Aaron and gathered together all the elders of the children of Israel: [30] And Aaron spake all the words which the LORD had spoken unto Moses, and did the signs in the sight of the people. [31] And the people believed: and when they heard that the LORD had visited the children of Israel, and that he had looked upon their affliction, then they bowed their heads and worshipped.
