New Revised Standard Version
“Moreover you know also what Joab son of Zeruiah did to me, how he dealt with the two commanders of the armies of Israel, Abner son of Ner, and Amasa son of Jether, whom he murdered, retaliating in time of peace for blood that had been shed in war, and putting the blood of war on the belt around his waist, and on the sandals on his feet.

Contemporary English Version
Solomon, don't forget what Joab did to me by killing Abner son of Ner and Amasa son of Jether, the two commanders of Israel's army. He killed them as if they were his enemies in a war, but he did it when there was no war. He is guilty, and now it's up to you to punish him
