24 On the journey back, as they camped for the night, God met Moses and would have killed him but 25 Zipporah took a flint knife and cut off her son's foreskin, and touched Moses' member with it. She said, "Oh! You're a bridegroom of blood to me!" 26 Then God let him go. She used the phrase "bridegroom of blood" because of the circumcision. 27 God spoke to Aaron, "Go and meet Moses in the wilderness." He went and met him at the mountain of God and kissed him. 28 Moses told Aaron the message that God had sent him to speak and the wonders he had commanded him to do.

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!
