1 Chronicles 11:6

The name and fresh glory of Joab, as given here, are not given in 2 Samuel 5:3-10 ; and we could suppose that they were purposely withheld there. It is true that Joab already held high office, probably the first place as captain of David's men, but Bertheau's objection to the statements of this verse on such grounds easily yields to the considerations—first, that there can be no doubt Joab had fallen into disfavour with David and others , upon his slaying of Abner ( 2 Samuel 3:26-29 , 2 Samuel 3:36 , 2 Samuel 3:37 ); and further, that this was a great occasion, exceedingly favourable for evoking any very special ability of younger or unknown men, at present lost under the shadow of larger growths. The advantage which Joab gained now was one that confirmed his position and increased largely his influence; and an indication that he was not slow to avail himself of it is probably to be traced in the eighth verse, where it is said while "David built… even from Millo round about,… Joab repaired the rest of the city."
