Thou knowest also what Joab the son of Sarvia hath done to me, what he did to the two captains of the army of Israel, to Abner the son of Ner, and to Amasa the son of Jether: whom he slew, and shed the blood of war in peace, and put the blood of war on his girdle that was about his loins, and in his shoes that were on his feet.
Rashi
[What] was done to me. By showing them the letter which Dovid had sent through Uryah, [according to] the Midrash Rabbi Tanchuma.
[And shed] the blood of war at a time of peace. Since they were at peace with him, they were not on guard against him.
On his belt which was on his loins. He had girded his sword, attached to his loins, not in the customary manner of those girding swords, when he went out to meet Amasa. [He placed the sword’s] opening downward so that it would fall out, as it is stated, “and he went out and it fell out.” Once it fell, he [Yo’av] retrieved it. Amasa presumed that he retrieved it only to pick it up from the ground, and he did not guard himself from the sword which was in Yo’av’s hand.
And in his shoe that was on his feet. He killed Avner cunningly by asking him, “How does a woman who has no hands remove the shoes?” as it is stated, “And Yo’av caused him to turn aside at the gate to speak with him בשלי.” [בשלי is] an expression of “remove [של] your shoes.”
