When Yo'av was come out from David, he sent messengers after Aviner, and they brought him back from the well of Sirah: but David didn't know it.
You know Aviner the son of Ner, that he came to deceive you, and to know your going out and your coming in, and to know all that you do.
When Aviner was returned to Chevron, Yo'av took him aside into the midst of the gate to speak with him quietly, and struck him there in the body, so that he died, for the blood of `Asa'el his brother.
