Answer to the question in Ecc 6:8. This is the advantage:
Better is the sight of the eyes - the wise man’s godly enjoyment of present seen blessings
than the (fool’s) wandering - literally, walking (Psa 73:9), of the desire, that is, vague, insatiable desires for what he has not (Ecc 6:7; Heb 13:5).
this - restless wandering of desire, and not enjoying contentedly the present (1Ti 6:6, 1Ti 6:8).
