Then Abner called to Joab and said, “Must the sword devour forever? Do you not know that the end will be bitterness? How long will it be then, before you tell the people to turn back from pursuing their brothers?” Bible see other translations

“the end will be bitterness.” Hand-to-hand combat has always been a nasty business, and here we see how close the opposing armies were because Abner and Joab are so close they can speak to each other. Abner was right of course. Israelite killing Israelite would only end in bitterness.
