'Shame' in the Bible

but we have renounced the things hidden because of shame, not walking in craftiness or adulterating the word of God, but by the manifestation of truth commending ourselves to every man’s conscience in the sight of God.

For if in anything I have boasted to him about you, I was not put to shame; but as we spoke all things to you in truth, so also our boasting before Titus proved to be the truth.

otherwise if any Macedonians come with me and find you unprepared, we—not to speak of you—will be put to shame by this confidence.

For even if I boast somewhat further about our authority, which the Lord gave for building you up and not for destroying you, I will not be put to shame,

To my shame I must say that we have been weak by comparison.But in whatever respect anyone else is bold—I speak in foolishness—I am just as bold myself.
