'Exposing' in the Bible

Many of those who had become believers were coming, confessing and disclosing their [former sinful] practices.

For, I think, God has exhibited us apostles at the end of the line, like men sentenced to death [and paraded as prisoners in a procession], because we have become a spectacle to the world [a show in the world’s amphitheater], both to angels and to men.

For the word of God is living and active and full of power [making it operative, energizing, and effective]. It is sharper than any two-edged sword, penetrating as far as the division of the soul and spirit [the completeness of a person], and of both joints and marrow [the deepest parts of our nature], exposing and judging the very thoughts and intentions of the heart.

and who have fallen away, as long as they continue to crucify the Son of God to their own detriment by exposing him to public ridicule.
