Ecclesiastes 2:14-15

14The wise man’s eyes are in his head, but the fool walks in darkness; and yet I know that [in the end] one fate happens to them both.

15Then I said to myself, “As it happens to the fool, so death will also happen to me. What use is it then for me to be extremely wise?” Then I said in my heart, “This too is vanity (meaningless).”
