Alma 46:30
Now Moroni thought it was not expedient that the Lamanites should have any more strength; therefore he thought to cut off the people of Amalickiah, or to take them and bring them back, and put Amalickiah to death; yea, for he knew that he would stir up the Lamanites to anger against them, and cause them to come to battle against them; and this he knew that Amalickiah would do that he might obtain his purposes.
