50 These are the sons of Aaron: Eleazar his son, Phinehas his son, Abishua his son,

The sons of Aaron - This list, a mere repetition of that in 1-Chronicles 6:3-8, came, probably, from a different source - a source belonging to the time of David, with whom Ahimaaz (the last name on the list) was contemporary. The other list 1-Chronicles 6:4-15 came, no doubt, from a document belonging to the time of the captivity (see 1-Chronicles 6:15).
These are the sons of Aaron - We have already had a list of these, (see 1-Chronicles 6:3-16); this is a second, but less extensive, and is a proof that the writer of this book had several lists before him, from which he borrowed as he judged proper.
(6:35-38). The remarks as to the service of the priests are followed by a catalogue of the high priests, which runs from Eleazar to Ahimaaz the son of Zadok (cf. 2-Samuel 15:27), who probably succeeded his father in the high-priesthood even in the time of Solomon. This genealogy is similar in form to the genealogies given in 1-Chronicles 6:20-30, and has therefore most probably been derived from the same source as this, and has been drawn in here to form a transition to the enumeration of the cities of the Levites; for it begins in 1-Chronicles 6:44 with the dwelling-places of the sons of Aaron, and the אהרן לבני...מושׁבותם ואלּה of 1-Chronicles 6:44 corresponds to the אהרן בּני ואלּה of 1-Chronicles 6:49. The order of the names coincides exactly with that of the longer register in 1 Chr 5:30-34.
