Ecclesiastes 2:19

"And who knows whether he will be. wise man or. fool? Yet he will have control over all the fruit of my labor for which. have labored by acting wisely under the sun. This too is vanity."who knows" -There isn't any guarantee! And this person will have complete control over everything which. have worked so hard for! In addition, if you can't trust your kids, brother-in-law, or some other relative-somebody is still going to get everything you have. You may establish. "foundation" or. "trust" and still somebody can come along and complete waste the fruits of all your hard work. The son that Solomon had wasn't the brightest of men (1 Kings 11:43-12:15). Eventually everything that Solomon had amassed would be wasted, destroyed or loss through the unfaithfulness of the men who followed him as the kings of Israel.

"for which. have labored by acting wisely" -"The more he has toiled at his life's work….the more galling will be the thought of its fruits falling into other hands---and as likely as not, the wrong hands" (Kidner p. 35). You can almost hear him saying, "It's not fair!"
