And who knoweth whether he shall be a wise [man] or a fool? yet shall he have rule over all my labour wherein I have laboured, and wherein I have shewed myself wise under the sun. This [is] also vanity.
Berean Study Bible (BSB) - Ecclesiastes 2:19 >And who knows whether that man will be wise or foolish? Yet he will take over all the labor at which I have worked skillfully under the sun. This too is futile.
