John Trapp on Psalms 73:20

Verſ. 20. As a dream when one awaketh] Such is the wicked mans pomp and bravery; now what are dreams but pleaſant follies and deluſions, the empty bubbles of the mind, Children and tales of fancy, idle and fruitleſs notions, meer bawbles?Sic Mycillus apud Lucian. See Iſa. 29.7, 8. The Fiſher-man in Theocritus dreamt that he was ſome demy-god; but when he awaked, all his golden hopes vaniſhed. The Chaldee explaineth it, As the dream of a drunken man; who ſleeping on the ſteep of a rock may think himſelf a King; and ſtarting for joy may ſoon break his neck at the bottom.

So, O Lord, when thou awakeſt thou ſhalt despiſe their image] That is, that whereof they dreamt, and whereon they do ſtill doat; viz. their worldly pomp and pride, which is nothing elſe but magnum nihil, a glorious phancy, a non-entity. Some read it thus, When thou ſhalt raiſe up (the dead) thou ſhalt despiſe their image, that is, their ſouls; they ſhall riſe to everlaſting ſhame and contempt, Dan. 12.2.
