18 Then Moses departed and returned to Jethro his father-in-law and said to him, "Please, let me go, that I may return to my brethren who are in Egypt, and see if they are still alive." And Jethro said to Moses, "Go in peace." 19 Now the LORD said to Moses in Midian, "Go back to Egypt, for all the men who were seeking your life are dead." 20 So Moses took his wife and his sons and mounted them on a donkey, and returned to the land of Egypt Moses also took the staff of God in his hand.
21 The LORD said to Moses, "When you go back to Egypt see that you perform before Pharaoh all the wonders which I have put in your power; but I will harden his heart so that he will not let the people go. 22 "Then you shall say to Pharaoh, 'Thus says the LORD, "Israel is My son, My firstborn. 23 "So I said to you, 'Let My son go that he may serve Me'; but you have refused to let him go Behold, I will kill your son, your firstborn."'"
24 Now it came about at the lodging place on the way that the LORD met him and sought to put him to death. 25 Then Zipporah took a flint and cut off her son's foreskin and threw it at Moses' feet, and she said, "You are indeed a bridegroom of blood to me." 26 So He let him alone. At that time she said, "You are a bridegroom of blood"--because of the circumcision.
27 Now the LORD said to Aaron, "Go to meet Moses in the wilderness " So he went and met him at the mountain of God and kissed him. 28 Moses 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. 29 Then Moses and Aaron went and assembled all the elders of the sons of Israel; 30 and Aaron spoke all the words which the LORD had spoken to Moses He then performed the signs in the sight of the people. 31 So the people believed; and when they heard that the LORD was concerned about the sons of Israel and that He had seen their affliction, then they bowed low and worshiped.
