2 Samuel 3:27-29

And when Abner was returned to Hebron, Joab took him aside into the midst of the gate to speak with him quietly, and smote him there in the body, so that he died, for the blood of Asahel his brother. And afterward, when David heard it, he said, I and my kingdom are guiltless before Jehovah for ever of the blood of Abner the son of Ner: let it fall upon the head of Joab, and upon all his father’s house; and let there not fail from the house of Joab one that hath an issue, or that is a leper, or that leaneth on a staff, or that falleth by the sword, or that lacketh bread.
