'Renounced' in the Bible

It was so, when the days of their feasting had run their course, that Job sent and sanctified them, and rose up early in the morning, and offered burnt offerings according to the number of them all. For Job said, "It may be that my sons have sinned, and renounced God in their hearts." Job did so continually.

You have renounced the covenant of your servant. You have defiled his crown in the dust.

But we have renounced the hidden things of shame, not walking in craftiness, nor handling the word of God deceitfully; but by the manifestation of the truth commending ourselves to every man's conscience in the sight of God.
