Moreover thou knowest how Joab the son of Zeruiah hath served me, and what he hath done to the two captains of the hosts of Israel - unto Abner the son of Ner, and unto Amasa the son of Jether - how he slew them and shed the blood of war in time of peace, and put the blood of war upon his girdle that was about his loins and in his shoes that were on his feet.

And king Solomon answered and said unto his mother, "Why dost thou ask Abishag the Shunammite for Adonijah? But rather ask for him the kingdom, seeing he is mine elder brother! Even for him ask it; and for Abiathar the priest, and for Joab the son of Zeruiah."
