'Swords' in the Bible

Evil men draw their swords and prepare their bows, to bring down the oppressed and needy, and to slaughter those who are godly.

Their swords will pierce their own hearts, and their bows will be broken.

For they did not conquer the land by their swords, and they did not prevail by their strength, but rather by your power, strength and good favor, for you were partial to them.

His words are as smooth as butter, but he harbors animosity in his heart. His words seem softer than oil, but they are really like sharp swords.
