Use weapons

1. Alma 24: 18
     18 And this they did, it being in their view a testimony to God, and also to men, that they never would use weapons again for the shedding of man’s blood; and this they did, vouching and covenanting with God, that rather than shed the blood of their brethren they would give up their own lives; and rather than take away from a brother they would give unto him; and rather than spend their days in idleness they would labor abundantly with their hands.
2. Alma 55: 17
     17 Yea, even to their women, and all those of their children, as many as were able to use a weapon of war, when Moroni had armed all those prisoners; and all those things were done in a profound silence.
