The Book Of Mormon

And behold, now it came to pass that those Lamanites were more angry because they had slain their brethren; therefore they swore vengeance upon the Nephites; and they did no more attempt to slay the people of Anti-Nephi-Lehi at that time.

But they took their armies and went over into the borders of the land of Zarahemla, and fell upon the people who were in the land of Ammonihah, and destroyed them.
