2 Samuel 2:26-28 Complete Jewish Bible (CJB)
26 Then Avner called out to Yo’av, “Must the sword go on devouring forever? Don’t you know that in the end it can produce only bitterness? How long will it be, then, before you tell the people to quit pursuing their brothers?” 27 Yo’av said, “As God lives, if you hadn’t said something, there is no doubt that the people would have kept following their brothers all night long.” 28 Then Yo’av sounded the shofar, and with that the people halted. They stopped pursuing Isra’el, and they stopped fighting.
