22 And you are to say to Pharaoh, The Lord says, Israel is the first of my sons: 23 And I said to you, Let my son go, so that he may give me worship; and you did not let him go: so now I will put the first of your sons to death.
24 Now on the journey, at the night's resting-place, the Lord came in his way and would have put him to death. 25 Then Zipporah took a sharp stone, and cutting off the skin of her son's private parts, and touching his feet with it, she said, Truly you are a husband of blood to me. 26 So he let him go. Then she said, You are a husband of blood because of the circumcision. 27 And the Lord said to Aaron, Go into the waste land and you will see Moses. So he went and came across Moses at the mountain of God, and gave him a kiss. 28 And Moses gave Aaron an account of all the words of the Lord which he had sent him to say, and of all the signs which he had given him orders to do. 29 Then Moses and Aaron went and got together all the chiefs of the children of Israel: 30 And Aaron said to them all the words the Lord had said to Moses, and did the signs before all the people. 31 And the people had faith in them; and hearing that the Lord had taken up the cause of the children of Israel and had seen their troubles, with bent heads they gave him worship.

Commentary on Exodus 4:18-23
(Read Exodus 4:18-23)
After God had appeared in the bush, he often spake to Moses. Pharaoh had hardened his own heart against the groans and cries of the oppressed Israelites; and now God, in the way of righteous judgment, hardens his heart against the teaching of the miracles, and the terror of the plagues. But whether Pharaoh will hear, or whether he will forbear, Moses must tell him, Thus saith the Lord. He must demand a discharge for Israel, Let my son go; not only my servant, whom thou hast no right to detain, but my son. It is my son that serves me, and therefore must be spared, must be pleaded for. In case of refusal I will slay thy son, even thy first-born. As men deal with God's people, let them expect so to be dealt with.
Commentary on Exodus 4:24-31
(Read Exodus 4:24-31)
God met Moses in anger. The Lord threatened him with death or sent sickness upon him, as the punishment of his having neglected to circumcise his son. When God discovers to us what is amiss in our lives, we must give all diligence to amend it speedily. This is the voice of every rod; it calls us to return to Him that smites us. God sent Aaron to meet Moses. The more they saw of God's bringing them together, the more pleasant their interview was. The elders of Israel met them in faith, and were ready to obey them. It often happens, that less difficulty is found than was expected, in such undertakings as are according to the will of God, and for his glory. Let us but arise and try at our proper work, the Lord will be with us and prosper us. If Israel welcomed the tidings of their deliverance, and worshipped the Lord, how should we welcome the glad tidings of redemption, embrace it in faith, and adore the Redeemer!
