2 Samuel 3:27-29 Modern English Version (MEV)
27 So Abner returned to Hebron, and Joab pulled him aside in the gateway so as to speak with him undisturbed. There he struck him in the midsection so that he died on account of the blood of Asahel, his brother.
28 Afterward when David heard of this, he said, “My kingdom and I are forever blameless before the Lord for the blood of Abner the son of Ner. 29 May it fall upon the head of Joab and upon all his father’s house. May the house of Joab never be without one who has a discharge, or who is a leper, or who leans on a staff, or who falls by the sword, or who lacks food.”
