Ecclesiastes 7:23-25

English Standard Version

²³ All this I have tested by wisdom. ^(A)I said, “I will be wise,” but it was far from me. ²⁴ That which has been is far off, and ^(B)deep, very deep; ^(C)who can find it out?

^25 (D)I turned my heart to know and to search out and to seek wisdom and the scheme of things, and to know the wickedness of folly and the foolishness that is madness.
