9 It is better to be content with what the eyes can see than for one’s heart always to crave more. This continual longing is futile—like chasing the wind.
Darby
9 Better is the seeing of the eyes than the wandering of the desire: this also is vanity and pursuit of the wind.
KJV
9 Better [is] the sight of the eyes than the wandering of the desire: this [is] also vanity and vexation of spirit.
