2 Samuel 3:25-27 Catholic Public Domain Version (CPDV)

25. Do you not know, about Abner, the son of Ner, that he came to you for this, so that he might deceive you, and might know of your departure and your return, and so that he might know all that you do?"

26. And so, Joab, going out from David, sent messengers after Abner, and he brought him back from the cistern of Sirah, without David knowing.

27. And when Abner had returned to Hebron, Joab took him alone to the middle of the gate, so that he might speak to him, but with deceit. And there, he stabbed him in the groin, and he died, in revenge for the blood of Asahel, his brother.
