I.We have here a genealogy, not an endless one, such as the apostle condemns (Ti1 1:4), for it ends in those two great patriots Moses and Aaron, and comes in here to show that they were Israelites, bone of their bone and flesh of their flesh whom they were sent to deliver, raised up unto them of their brethren, as Christ also should be, who was to be the prophet and priest, the Redeemer and lawgiver, of the people of Israel, and whose genealogy also, like this, was to be carefully preserved. The heads of the houses of three of the tribes are here named, agreeing with the accounts we had, Gen. 46. Dr. Lightfoot thinks that Reuben, Simeon, and Levi, are thus dignified here by themselves for this reason, because they were left under marks of infamy by their dying father, Reuben for his incest and Simeon and Levi for their murder of the Shechemites; and therefore Moses would put this particular honour upon them, to magnify God's mercy in their repentance and remission, as a pattern to those that should afterwards believe: the two former seem rather to be mentioned only for the sake of a third, which was Levi, from whom Moses and Aaron descended, and all the priests of the Jewish church. Thus was the tribe of Levi distinguished betimes. Observe here, 1. That Kohath, from whom Moses and Aaron, and all the priests, derived their pedigree, was a younger son of Levi, Exo 6:16. Note, The grants of God's favours do not go by seniority of age and priority of birth, but the divine sovereignty often prefers the younger before the elder, so crossing hands. 2. That the ages of Levi, Kohath, and Amram, the father, grandfather, and great grandfather, of Moses, are here recorded; they all lived to a great age, Levi to 137, Kohath to 133, and Amram to 137. Moses himself came much short of them, and fixed seventy or eighty for the ordinary stretch of human life (Psa 90:10); for now that God's Israel was multiplied and had become a great nation, and divine revelation was by the hand of Moses committed to writing and no longer trusted to tradition, the two great reasons for the long lives of the patriarchs had ceased, and therefore henceforward fewer years must serve men. 3. That Aaron married Elisheba (the same name with that of the wife of Zecharias, Elizabeth, as Miriam is the same with Mary), daughter of Amminadab, one of the chief of the fathers of the tribe of Judah; for the tribes of Levi and Judah often intermarried, Exo 6:23. 4. It must not be omitted that Moses has recorded the marriage of his father Amram with Jochebed his own aunt (Exo 6:20); and it appears by Num 26:59 that it must be taken strictly for his father's own sister, at least by the half blood. This marriage was afterwards forbidden as incestuous (Lev 18:12), which might be looked upon as a blot upon his family, though before that law; yet Moses does not conceal it, for he sought not his own praise, but wrote with a sincere regard to truth, whether it smiled or frowned upon him. 5. He concludes it with a particular mark of honour on the persons he is writing of, though he himself was one of them, Exo 6:26, Exo 6:27. These are that Moses and Aaron whom God pitched upon to be his plenipotentiaries in this treaty. These were those to whom God spoke (Exo 6:26), and who spoke to Pharaoh on Israel's behalf, Exo 6:27. Note, Communion with God and serviceableness to his church are things that, above any other, put true honour upon men. Those are great indeed with whom God converses and whom he employs on his service. Such were that Moses and Aaron; and something of this honour have all his saints, who are made to our God kings and priests.

II.In the close of the chapter Moses returns to his narrative, from which he had broken off somewhat abruptly (Exo 6:13), and repeats, 1. The charge God had given him to deliver his message to Pharaoh (Exo 6:29): Speak all that I say unto thee, as a faithful ambassador. Note, Those that go on God's errand must not shun to declare the whole counsel of God. 2. His objection against it, Exo 6:30. Note, Those that have at any time spoken unadvisedly with their lips ought often to reflect upon it with regret, as Moses seems to do here.

Korah - Though he became a rebel against God and Moses, (see Num 16:1, etc)., yet Moses, in his great impartiality, inserts his name among those of his other progenitors.

And the sons of Korah,.... The eldest son of Izhar, who, though he proved a bad man, yet many of his posterity were good men, and are often mentioned in general in the titles of some of the psalms of David: the immediate sons of Korah were

Assir, and Elkanah, and Abiasaph. Aben Ezra says, that Samuel the prophet was of the sons of Korah; perhaps what might lead him to it was, because his father's name was Elkanah, the name of one of these sons of Korah, but cannot be this Elkanah:

these are the families of the Korhites; the heads of them, or from whom they descended.

Amram took him Jochebed his father's sister to wife--The Septuagint and Syriac versions render it "his cousin."
