2 Samuel 2:28

Then 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?

And 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.

And 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.

And Joab returned from following Abner: and when he had gathered all the people together, there lacked of David’s servants nineteen men and Asahel.
