'Shed' 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 king said to him, “Do just as he says. Strike him down and bury him in order to remove from me and from my father’s house the blood that Joab shed without just cause.
