Ecclesiastes 7:23-25

Revised Standard Version

²³ All this I have tested by wisdom; I said, “I will be wise”; but it was far from me. ²⁴ That which is, is far off, and deep, very deep; who can find it out? ²⁵ I turned my mind to know and to search out and to seek wisdom and the sum of things, and to know the wickedness of folly and the foolishness which is madness.
