2 Samuel 2:27-31

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.

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

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.

But the servants of David had smitten of Benjamin, and of Abner’s men, so that three hundred and threescore men died.
