'Integrity' in the Bible

He layeth up sound wisdom for the upright; He is a shield to them that walk in integrity;

The integrity of the upright shall guide them; But the perverseness of the treacherous shall destroy them.

Better is the poor that walketh in his integrity Than he that is perverse in his lips and is a fool.

A righteous man that walketh in his integrity, Blessed are his children after him.

Better is the poor that walketh in his integrity, Than he that is perverse in his ways, though he be rich.
