Ecclesiastes 6:9 - Coke's Commentary on the Holy Bible

Better is the sight of the eyes— The third and last proof, contained in this and the two preceding verses, is taken from the insatiableness of mens' wishes, whereby they are made miserable even when they get the utmost of what they can reasonably wish for. It is a vain and foolish thing to give a loose to your desires, instead of being satisfied with what you at present enjoy; since, whatever you may wish for, it is impossible for you personally to enjoy more than what your constitution will bear; and that is very little, properly speaking, beyond the necessaries of life, which are enjoyed by every man upon earth, whether his wishes be extensive or not.
