Alma 19:20-22

20 But others rebuked them, saying: The king hath brought this evil upon his house, because he slew his servants who had had their flocks scattered at the waters of Sebus.

21 And they were also rebuked by those men who had stood at the waters of Sebus and scattered the flocks which belonged to the king, for they were angry with Ammon because of the number which he had slain of their brethren at the waters of Sebus, while defending the flocks of the king.

22 Now, one of them, whose brother had been slain with the sword of Ammon, being exceedingly angry with Ammon, drew his sword and went forth that he might let it fall upon Ammon, to slay him; and as he lifted the sword to smite him, behold, he fell dead.

Sometimes I can't believe this is NOT fiction!
