To disown.

Therefore seeing we have this ministry, as we have received mercy, we faint not; but have RENOUNCED the hidden things of dishonesty, not walking in craftiness, nor handling the word of God deceitfully; but by manifestation of the truth commending ourselves to every man's conscience in the sight of God. ( 2 Corinthians 1:1 Isaiah 4:1-2 )
