2 Samuel 3:27-29 Common English Bible (CEB)
27 When Abner returned to Hebron, Joab took him aside next to[a] the gate to speak with him in private. But instead Joab stabbed Abner in the stomach, and he died for shedding the blood of Asahel, Joab’s brother.
28 When David heard about this later, he said, “I and my kingdom are forever innocent before the Lord concerning the shedding of the blood of Abner, Ner’s son. 29 May it fall upon the head of Joab and his entire family tree! May Joab’s family never be without someone with a discharge or a skin disease,[b] someone who uses a crutch,[c] someone who dies by the sword, or someone who is hungry!”
