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).
