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.

Jewish Publication Society of America Version (JPS1917) - Ecclesiastes 2:19 >

And who knoweth whether he will be a wise man or a fool? yet will he have rule over all my labour wherein I have laboured, and wherein I have shown myself wise under the sun. This also is vanity.
