'Willfully' in the Bible

The foolish woman is restless and noisy;She is naive and easily misled and thoughtless, and knows nothing at all [of eternal value].

The perverse in heart are repulsive and shamefully vile to the Lord,But those who are blameless and above reproach in their walk are His delight!

He who [willfully] separates himself [from God and man] seeks his own desire,He quarrels against all sound wisdom.

Better is the poor who walks in his integrityThan he who is crooked and two-faced though he is rich.

A man who is burdened with the guilt of human blood (murder)Will be a fugitive until death; let no one support him or give him refuge.

He who walks blamelessly and uprightly will be kept safe,But he who is crooked (perverse) will suddenly fall.
