24 On the way to Egypt, at a place where Moses and his family had stopped for the night, the Lord confronted him and was about to kill him. 25 But Moses' wife, Zipporah, took a flint knife and circumcised her son. She touched his feet with the foreskin and said, "Now you are a bridegroom of blood to me." 26 (When she said "a bridegroom of blood," she was referring to the circumcision.) After that, the Lord left him alone. 27 Now the Lord had said to Aaron, "Go out into the wilderness to meet Moses." So Aaron went and met Moses at the mountain of God, and he embraced him. 28 Moses then told Aaron everything the Lord had commanded him to say. And he told him about the miraculous signs the Lord had commanded him to perform.

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!
