Exodus 4:21-31

21The Lord said to Moses, “When you return to Egypt, see that you perform before Pharaoh all the wonders (miracles) which I have put in your hand, but I will harden his heart and make him stubborn so that he will not let the people go.

22Then you shall say to Pharaoh, ‘Thus says the Lord, “Israel is My son, My firstborn.

23So I say to you, ‘Let My son go so that he may serve Me’; and if you refuse to let him go, behold, I will kill your son, your firstborn.” ’ ”

24Now it happened at the lodging place, that the Lord met Moses and sought to kill him [making him deathly ill because he had not circumcised one of his sons].

25Then Zipporah took a flint knife and cut off the foreskin of her son and threw it at Moses’ feet, and said, “Indeed you are a husband of blood to me!”

26So He let Moses alone [to recover]. At that time Zipporah said, “You are a husband of blood”—because of the circumcision.

27The Lord said to Aaron, “Go into the wilderness to meet Moses.” So he went and met him at the mountain of God (Sinai) and kissed him.

28Moses told Aaron all the words of the Lord with which He had sent him, and all the signs that He had commanded him to do.

29Then Moses and Aaron went [into Egypt] and assembled all the elders of the Israelites;

30and Aaron said all the words which the Lord had spoken to Moses. Then Moses performed the signs [given to him by God] before the people.

31So the people believed; and when they heard that the Lord was concerned about the Israelites and that He had looked [with compassion] on their suffering, then they bowed their heads and worshiped [the Lord].
