Matthew Henry on Exodus 4:24–end
Moses is here going to Egypt, and we are told,
I. How God met him in anger, Exo 4:24-26. This is a very difficult passage of story; much has been written, and excellently written, to make it intelligible; we will try to make it improving. Here is,
1. The sin of Moses, which was neglecting to circumcise his son. This was probably the effect of his being unequally yoked with a Midianite, who was too indulgent of her child, while Moses was too indulgent of her. Note, (1.) We have need to watch carefully over our own hearts, lest fondness for any relation prevail above our love to God, and take us off from our duty to him. It is charged upon Eli that he honoured his sons more than God (Sa1 2:29)…

Moses and Aaron went--towards Egypt, Zipporah and her sons having been sent back. (Compare Exo 18:2).
gathered . . . all the elders--Aaron was spokesman, and Moses performed the appointed miracles--through which "the people" (that is, the elders) believed (Kg1 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.

Adam Clarke on Exodus 4:30
Aaron spake all the words - It is likely that Aaron was better acquainted with the Hebrew tongue than his brother, and on this account he became the spokesman. See Clarke on Exo 4:14 (note).
Did the signs - Turned the rod into a serpent, made the hand leprous, and changed the water into blood. See Clarke on Exo 4:6 (note) and Exo 4:8 (note).
John Gill on Exodus 4:30
And Aaron spake all the words which the Lord had spoken unto Moses,.... As Moses had related to him, being his mouth and spokesman:
and did the signs in the sight of the people; not Aaron, but Moses, and these were the turning of his rod into a serpent, and the serpent into a rod again; putting his hand into and out of his bosom, when it was leprous, and then doing the same when it was well again; and taking water out of the river, and changing it into blood, which he did for the confirmation of his mission.
