2 Samuel 2:27 KJV

25And the children of Benjamin gathered themselves together after Abner, and became one troop, and stood on the top of an hill.

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, unless thou hadst spoken, surely then in the morning the people had gone up every one from following his brother.

28So Joab blew a trumpet, and all the people stood still, and pursued after Israel no more, neither fought they any more.

29And Abner and his men walked all that night through the plain, and passed over Jordan, and went through all Bithron, and they came to Mahanaim.
