'Swords' in the Bible

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

His buttery words are smooth,but war is in his heart.His words are softer than oil,but they are drawn swords.

I am surrounded by lions;I lie down with those who devour men.Their teeth are spears and arrows;their tongues are sharp swords.

who sharpen their tongues like swordsand aim bitter words like arrows,
