1 Kings 2:5

5 “You know what Joab son of Zeruiah did to me – how he murdered two commanders of the Israelite armies, Abner son of Ner and Amasa son of Jether.
Heb “what he did to the two commanders…and he killed them.”
During peacetime he struck them down like he would in battle;
Heb “he shed the blood of battle in peace.”
when he shed their blood as if in battle, he stained his own belt and the sandals on his feet.
Heb “and he shed the blood of battle when he killed which is on his waist and on his sandal[s] which are on his feet.” That is, he covered himself with guilt and his guilt was obvious to all who saw him.
