Biblical Non-Violence

Many years ago someone taught me that if you are having a serious problem with another person you can use a verse from the Bible: Psalm 2.9 (Thou shalt break them with a rod of iron; Thou shalt dash them to pieces like a potter’s vessel) and it will help the situation.
I was thinking about the vow of non-violence that you spoke about on your web site, and I was wondering if applying these verses to a situation would be considered violent?
