Ecclesiastes 7:23-25

New International Version

“I am determined to be wise”^(A)—
    but this was beyond me.
²⁴ Whatever exists is far off and most profound—
    who can discover it?^(B)
25 So I turned my mind to understand,
    to investigate and to search out wisdom and the scheme of things^(C)
and to understand the stupidity of wickedness
    and the madness of folly.^(D)
