Ecclesiastes 2:15

Then said I in my heart, as it happeneth to the fool, so it
happeneth even to me
The wisest of kings, and the wisest of men; that is, he looked over things in his mind, and considered what had befallen him, or what were his present circumstances, or what would be his case, especially at death; and said within himself, the same things happen to me, who have attained to the highest pitch of wisdom, as to the most errant fool; and therefore no true happiness can be in this sort of wisdom. The Targum paraphrases it thus,

``as it happened to Saul the son of Kish, the king who turned aside perversely, and kept not the commandment he received concerning Amalek, and his kingdom was taken from him; so shall it happen to me;''

and why was I then more wise?
the Targum adds, than he, or than any other man, or even than a fool; why have I took so much pains to get wisdom? what am I the better for it? what happiness is there in it, seeing it gives me no advantage, preference, and excellency to a fool; or secures me from the events that befall me? Then I said in my heart, that this also [is] vanity;
this worldly wisdom has nothing solid and substantial in it, as well as pleasure; and it is a vain thing to seek happiness in it, since this is the case, that the events are the same to men that have it, as to one that has it not.
