Job 4:6 - Ellicott's Commentary On The Whole Bible

Is not this thy fear, thy confidence...? — The meaning seems to be, “Should not thy fear or piety be thy confidence, and the uprightness of thy ways thy hope? Should not the piety thou wast so ready to commend to others supply a sufficient ground of hope for thyself?” Or we may understand, “Is not thy reverence, thy confidence, thy hope, and thy integrity shown to be worthless if thou faintest as soon as adversity toucheth thee?” The drift of the speaker is virtually the same in either case.
