2 Samuel 2:26-31

26Then Abner called to Joab, and said, Shall the sword devour for ever? knowest thou not that it will be bitterness in the latter end? how long shall it be then, ere thou bid the people return from following their brethren? 27And Joab said, As God liveth, if thou hadst not spoken, surely then in the morning the people had gone away, nor followed every one his brother. 28So Joab blew the trumpet; and all the people stood still, and pursued after Israel no more, neither fought they any more. 29And Abner and his men went all that night through the Arabah; and they passed over the Jordan, and went through all Bithron, and came to Mahanaim.

30And Joab returned from following Abner: and when he had gathered all the people together, there lacked of David’s servants nineteen men and Asahel. 31But the servants of David had smitten of Benjamin, and of Abner’s men, so that three hundred and threescore men died.
