2 Samuel 3:31

David said to Joab and all the people, &c. The command was especially given to Joab, to bring him to repentance for his sin, and to expose him to public shame. Rend your clothes and gird you with sackcloth, &c. These were all outward expressions of very great sorrow, which Joab himself was forced, however reluctant, to make a show of. And King David himself followed the bier Was the chief mourner, attending upon the corpse, and paying Abner that respect which was due to his quality. Though this was contrary to the usage of kings, and might seem below David's dignity; yet it was now expedient to vindicate himself from all suspicion of concurrence in this action. The word המשׂה, hammittah, here rendered the bier, properly means the bed. It was that on which persons of quality were wont to be carried forth to their graves, as ordinary people were upon what we call a bier.
