Ok, I think this is what I was thinking of as being more recent, a Study edition Watchtower from 2011. Sorry for the cut and paste, I took the quote from another site. I really hate clicking on the official site!
Nov 15, 2011 WT - "The prophet Elisha sent one of the sons of the prophets to anoint Jehu as king and to intruct him to kill every male of the apostate house of Ahab.—2 Ki. 8:28; 9:1-10." "Though the thought of violence is unpleasant, we should realize that in those days, Jehovah used his servants to carry out his judgments.... Today, no servant of Jehovah uses physical force against opponents of pure worship. “Vengeance is mine,” God says. (Heb.10:30) But to rid the congregation of potentially corrupting influences, Christian elders may have to act with courage similar to that of Jehu.

"Jehu announced that he intended to hold “a great sacrifice” for Baal. (2 Ki. 10:18, 19) “This is a clever play on words on the part of Jehu,” says one scholar. While the term employed here “generally means ‘sacrifice,’ it is also used of the ‘slaughter’ of apostates.” "It is true that Jehu spilled much blood. Yet, the Scriptures present him as a courageous man.
