Matthew Henry on 1 Chronicles 6:1-30
The priests and Levites were more concerned than any other Israelites to preserve their pedigree clear and to be able to prove it, because all the honours and privileges of their office depended upon their descent. And we read of those who, though perhaps they really were children of the priests, yet, because they could not find the register of their genealogies, nor make out their descent by any authentic record, were, as polluted, put from the priesthood, and forbidden to eat of the holy things, Ezr 2:62, Ezr 2:63. It is but very little that is here recorded of the genealogies of this sacred tribe. I. The first fathers of it are here named twice, Ch1 6:1, Ch1 6:16. Gershom, Kohath, and Mer…

Adam Clarke on 1 Chronicles 6:10

John Gill on 1 Chronicles 6:3
And the children of Amram, Aaron, and Moses, and Miriam,.... Very memorable persons: Aaron was the high priest, Moses the prophet and lawgiver, and Miriam a prophetess, see Micah 6:4,
the sons also of Aaron, Nadab and Abihu, Eleazar and Ithamar; the two first were destroyed by fire from heaven for offering strange fire, Leviticus 10:1 and the third succeeded his father in the high priesthood; the line of which is drawn from Aaron through him unto the Babylonish captivity, from hence to the end of the fifteenth verse, where it ends: Jehozadak is the same with Josedech, Haggai 1:1 who went young into Babylon, and whose son Joshua, born in the captivity, came out of it on the proclamation of C…
