Exodus 4:21-31

21The Lord instructed Moses, “When you go back to Egypt, make sure you do before Pharaoh all the wonders that I have put within your power. But I will harden his heart so that he won’t let the people go.

22And you will say to Pharaoh: This is what the Lord says: Israel is my firstborn son.

23I told you: Let my son go so that he may worship me, but you refused to let him go. Look, I am about to kill your firstborn son!”

24On the trip, at an overnight campsite, it happened that the Lord confronted him and intended to put him to death.

25So Zipporah took a flint, cut off her son’s foreskin, threw it at Moses’s feet, and said, “You are a bridegroom of blood to me!”

26So he let him alone. At that time she said, “You are a bridegroom of blood,” referring to the circumcision.

27Now the Lord had said to Aaron, “Go and meet Moses in the wilderness.” So he went and met him at the mountain of God and kissed him.

28Moses told Aaron everything the Lord had sent him to say, and about all the signs he had commanded him to do.

29Then Moses and Aaron went and assembled all the elders of the Israelites.

30Aaron repeated everything the Lord had said to Moses and performed the signs before the people.

31The people believed, and when they heard that the Lord had paid attention to them and that he had seen their misery, they knelt low and worshiped.
