'Weapons' in the Bible

in [speaking] the word of truth, in the power of God; by the weapons of righteousness for the right hand [like holding the sword to attack] and for the left [like holding the shield to defend],

For though we walk in the flesh [as mortal men], we are not carrying on our [spiritual] warfare according to the flesh and using the weapons of man.

The weapons of our warfare are not physical [weapons of flesh and blood]. Our weapons are divinely powerful for the destruction of fortresses.
