2 Samuel 2:27 WEB

²⁵  The children of Benjamin gathered themselves together after Abner, and became one band, and stood on the top of a hill.

²⁶  Then Abner called to Joab, and said, 'Shall the sword devour forever? Don't you know that it will be bitterness in the latter end? How long shall it be then, before you bid the people return from following their brothers?'

²⁷  Joab said, As God lives, if you had not spoken, surely then in the morning the people had gone away, nor followed everyone his brother.

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

²⁹  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.
