2. Alma 49: 22

3. Alma 55: 23
     23 And thus they saw that the Nephites had power over them; and in these circumstances they found that it was not expedient that they should fight with the Nephites; therefore their chief captains demanded their weapons of war, and they brought them forth and cast them at the feet of the Nephites, pleading for mercy.
