King James Version
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.English Standard Version
and who knows whether he will be wise or a fool? Yet he will be master of all for which I toiled and used my wisdom under the sun. This also is vanity.New International Version
And who knows whether he will be a wise man or a fool? Yet he will have control over all the work into which I have poured my effort and skill under the sun. This too is meaningless.
