2 Samuel 3:25-27

Young's Literal Translation

²⁵ Thou hast known Abner son of Ner, that to deceive thee he came, and to know thy going out and thy coming in, and to know all that thou art doing.'

²⁶ And Joab goeth out from David, and sendeth messengers after Abner, and they bring him back from the well of Sirah, and David knew not.

²⁷ And Abner turneth back to Hebron, and Joab turneth him aside unto the midst of the gate to speak with him quietly, and smiteth him there in the fifth [rib] -- and he dieth -- for the blood of Asahel his brother.
