Parallel
Ecclesiastes 2:15
Brenton's English Septuagint · Berean Standard Bible
And I said in my heart, As the event of the fool is, so shall it be to me, even to me; and to what purpose have I gained wisdom? I said moreover in my heart, This is also vanity, because the fool speaks of his abundance.
So I said to myself, “The fate of the fool will also befall me. What then have I gained by being wise?” And I said to myself that this too is futile.
