'Murdered' in the Bible

“You also know what Joab son of Zeruiah did to me and what he did to the two commanders of Israel’s army, Abner son of Ner and Amasa son of Jether. He murdered them in a time of peace to avenge blood shed in war. He spilled that blood on his own waistband and on the sandals of his feet.

The Lord will bring back his own blood on his head because he struck down two men more righteous and better than he, without my father David’s knowledge. With his sword, Joab murdered Abner son of Ner, commander of Israel’s army, and Amasa son of Jether, commander of Judah’s army.

Tell him, ‘This is what the Lord says: Have you murdered and also taken possession?’ Then tell him, ‘This is what the Lord says: In the place where the dogs licked Naboth’s blood, the dogs will also lick your blood!’”
