Exodus 4:21-31

21The Lord said to Moses, “When you go back to Egypt, see that you do before Pharaoh all the wonders I have put under your control. But I will harden his heart and he will not let the people go.

22You must say to Pharaoh, ‘Thus says the Lord, “Israel is my son, my firstborn,

23and I said to you, ‘Let my son go that he may serve me,’ but since you have refused to let him go, I will surely kill your son, your firstborn!”’”

24Now on the way, at a place where they stopped for the night, the Lord met Moses and sought to kill him.

25But Zipporah took a flint knife, cut off the foreskin of her son and touched it to Moses’ feet, and said, “Surely you are a bridegroom of blood to me.”

26So the Lord let him alone. (At that time she said, “A bridegroom of blood,” referring to the circumcision.)

27The Lord said to Aaron, “Go to the wilderness to meet Moses. So he went and met him at the mountain of God and greeted him with a kiss.

28Moses told Aaron all the words of the Lord who had sent him and all the signs that he had commanded him.

29Then Moses and Aaron went and brought together all the Israelite elders.

30Aaron spoke all the words that the Lord had spoken to Moses and did the signs in the sight of the people,

31and the people believed. When they heard that the Lord had attended to the Israelites and that he had seen their affliction, they bowed down close to the ground.
