24 On the way, at a place where they spent the night, the Lord met him and tried to kill him. 25 But Zipporah took a flint and cut off her son's foreskin, and touched Moses' feet with it, and said, "Truly you are a bridegroom of blood to me!" 26 So he let him alone. It was then she said, "A bridegroom of blood by circumcision." 27 The Lord said to Aaron, "Go into the wilderness to meet Moses." So he went; and he met him at the mountain of God and kissed him. 28 Moses told Aaron all the words of the Lord with which he had sent him, and all the signs with which he had charged him.

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!
