As a dream when one awaketh; so, O Lord, when thou awakest, thou shalt despise their image. As a dream when one awaketh - So their goods fled away. Their possession was a dream - their privation, real.
Thou shalt despise their image - While destitute of true religion, whatever appearance they had of greatness, nobility, honor, and happiness; yet in the sight of God they had no more than the ghost or shade of excellence which God is said here to despise. Who would be rich at such risk and dishonor?
