4:18 So Moses went back to his father-in-law Jethro and said to him, “Let me go, so that I may return to my relatives in Egypt and see if they are still alive.” Jethro said to Moses, “Go in peace.” 4:19 The Lord said to Moses in Midian, “Go back to Egypt, because all the men who were seeking your life are dead.” 4:20 Then Moses took his wife and sons and put them on a donkey and headed back to the land of Egypt, and Moses took the staff of God in his hand. 4:21 The 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. 4:22 You must say to Pharaoh, ‘Thus says the Lord, “Israel is my son, my firstborn, 4:23 and 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!”’”
4:24 Now on the way, at a place where they stopped for the night, the Lord met Moses and sought to kill him. 4:25 But 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.” 4:26 So the Lord let him alone. (At that time she said, “A bridegroom of blood,” referring to the circumcision.)
4:27 The 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. 4:28 Moses told Aaron all the words of the Lord who had sent him and all the signs that he had commanded him. 4:29 Then Moses and Aaron went and brought together all the Israelite elders. 4:30 Aaron spoke all the words that the Lord had spoken to Moses and did the signs in the sight of the people, 4:31 and 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.
