what is the example of violence language in much ado about nothing?

The men have just returned from war. Although "love" is in the air, the language of war and violence seem imbedded in the language. There are quite a few examples. Claudio seems intent on destroying his love Hero on pretty flimsy evidence of her infidelity. Leonato accuses Claudio of killing Hero with words, “Thy slander hath gone through and through her heart”. When Borachio confesses to inventing Hero's affair, Don Pedro says that the truth, in all its dark glory, is like a sword that pierces young Claudio’s heart, “Runs not this speech like iron through your blood? There is, of course the battle of wits between Beatrice and Bennedick. Every time the two characters share the stage there comes a "merry war" with words, "they never meet but there's a skirmish of wit between them”.
