“Moreouer thou knowest also what Ioab the sonne of Zeruiah did to mee, and what he did to the two captaines of the hostes of Israel, vnto Abner the sonne of Ner, and vnto Amasa the sonne of Iether, whom hee slewe, and shed the blood of warre in peace, and put the blood of warre vpon his girdle that was about his loynes, and in his shooes that were on his feet.”
1611 King James Version (KJV)
2:5 To me - That is, against me; in what he did against Abner andAmasa: whose death was a great injury to David, as it was a breachof his laws and peace; a contempt of his person and government; a perniciousexample to his subjects, and a great scandal to him, as if Joab had beenonly David's instrument, to affect what he secretly designed.And shed - He slew them as if they had been in the state of war, whenthere was not only a cessation of arms, but also a treaty of peace. Putthe blood - This is added to note his impenitency, that although by hisperfidious manner of killing them when he pretended to embrace them, hestained his own garments with their blood, yet he was not ashamed of it, butgloried in it, and marched boldly along with the army, with the same girdleand shoes which were sprinkled with their blood.
