English Standard Version
Chapter 3 28
Afterward, when David heard of it, he said, “I and my kingdom are forever guiltless 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, and may the house of Joab never be without one who has a discharge or who is leprous or who holds a spindle or who falls by the sword or who lacks bread!” 30
So Joab and Abishai his brother killed Abner, because he had put their brother Asahel to death in the battle at Gibeon. 31
Then David said to Joab and to all the people who were with him, “Tear your clothes and put on sackcloth and mourn before Abner.” And King David followed the bier.
