2 Samuel 3:27-29 Darby Translation (DARBY)
27 And when Abner was returned to Hebron, Joab took him aside in the gate to speak with him secretly, and smote him there in the belly, that he died, for the blood of Asahel his brother.
28 And afterwards David heard [it], and he said, I and my kingdom are guiltless before Jehovah for ever from the blood of Abner the son of Ner:
29 let it fall on the head of Joab, and on all his father's house; and let there not fail from the house of Joab one that has an issue, or that is a leper, or that leans on a staff, or that falls by the sword, or that lacks bread!
2 Samuel 3:27-29 New International Version (NIV)
27 Now when Abner returned to Hebron, Joab took him aside into an inner chamber, as if to speak with him privately. And there, to avenge the blood of his brother Asahel, Joab stabbed him in the stomach, and he died.
28 Later, when David heard about this, he said, “I and my kingdom are forever innocent before the Lord concerning the blood of Abner son of Ner. 29 May his blood fall on the head of Joab and on his whole family! May Joab’s family never be without someone who has a running sore or leprosy[a] or who leans on a crutch or who falls by the sword or who lacks food.”
