2 Samuel 3:26-30 - Joab Murders Abner
26 And Joab will go forth from David and send messengers after Abner, and they will turn him back from the Well of Sirah: and David knew not 27 And Abner will turn back to Hebron, and Joab will turn him away to the midst of the gate to speak with him in quiet, and he will strike him there in the belly, and he will die for the blood of Asahel his brother.
28 And David will hear from after this, and he will say, I am innocent, and my kingdom, with Jehovah even forever, from the bloods of Abner son of Ner. 29 It will stay upon the head of Joab and to all the house of his father; and there shall not be cut off from the house of Joab, him flowing, and the leprous, and him holding fast upon a staff, and him falling upon a sword, and him diminished in bread. 30 And Joab and Abishai his brother killed Abner because be slew Asahel their brother in Gibeon in war.
