'Speaking' 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],

But even if I am unskilled in speaking, yet I am not [untrained] in knowledge [I know what I am talking about]; but we have made this evident to you in every way, in all things.

To my shame, I must say, we have been too weak [in comparison to those pseudo-apostles who take advantage of you].But in whatever anyone else dares to boast—I am speaking foolishly—I also dare to boast.

If I wish to boast, I will not be foolish, because I will be speaking the truth. But I abstain [from it], so that no one will credit me with more than [is justified by what] he sees in me or hears from me.

Now I have become foolish; you have forced me [by questioning my apostleship]. Actually I should have been commended by you [instead of being treated disdainfully], for I was not inferior to those super-apostles, even if I am nobody.

All this time you have been thinking that we are [merely] defending ourselves to you. It is in the sight of God that we have been speaking [as one] in Christ; and everything, dearly beloved, is to strengthen you [spiritually].
