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!
29-31. Moses and Aaron went—towards Egypt, Zipporah and her sons having been sent back. (Compare Ex 18:2).
gathered … all the elders—Aaron was spokesman, and Moses performed the appointed miracles—through which "the people" (that is, the elders) believed (1Ki 17:24; Jos 3:2) and received the joyful tidings of the errand on which Moses had come with devout thanksgiving. Formerly they had slighted the message and rejected the messenger. Formerly Moses had gone in his own strength; now he goes leaning on God, and strong only through faith in Him who had sent him. Israel also had been taught a useful lesson, and it was good for both that they had been afflicted.
