[18] Then Moses went back to Jethro his father-in-law and said to him, “Let me return to my own people in Egypt to see if any of them are still alive.” Jethro said, “Go, and I wish you well.” [19] Now the LORD had said to Moses in Midian, “Go back to Egypt, for all those who wanted to kill you are dead.” [20] So Moses took his wife and sons, put them on a donkey and started back to Egypt. And he took the staff of God in his hand. [21] The LORD said to Moses, “When you return to Egypt, see that you perform before Pharaoh all the wonders I have given you the power to do. But I will harden his heart so that he will not let the people go. [22] Then say to Pharaoh, ‘This is what the LORD says: Israel is my firstborn son, [23] and I told you, “Let my son go, so he may worship me.” But you refused to let him go; so I will kill your firstborn son.’ ” [24] At a lodging place on the way, the LORD met Moses and was about to kill him. [25] But Zipporah took a flint knife, cut off her son’s foreskin and touched Moses’ feet with it. “Surely you are a bridegroom of blood to me,” she said. [26] So the LORD let him alone. (At that time she said “bridegroom of blood,” referring to circumcision.) [27] The LORD said to Aaron, “Go into the wilderness to meet Moses.” So he met Moses at the mountain of God and kissed him. [28] Then Moses told Aaron everything the LORD had sent him to say, and also about all the signs he had commanded him to perform. [29] Moses and Aaron brought together all the elders of the Israelites, [30] and Aaron told them everything the LORD had said to Moses. He also performed the signs before the people, [31] and they believed. And when they heard that the LORD was concerned about them and had seen their misery, they bowed down and worshiped.
