'Defending' in the Bible

My reply was that it is not the custom among the Romans to give up any one for punishment before the accused has had his accusers face to face, and has had an opportunity of defending himself against the charge which has been brought against him.

who do shew the work of the law written in their hearts, their conscience also witnessing with them, and between one another the thoughts accusing or else defending,

You have thought all along that we were defending ourselves to you. No, in the sight of God we are speaking in Christ, and everything, dear friends, is for building you up.
