Ecclesiastes 7:21-25

Also, do not take seriously all the words which are spoken, so that you do not hear your servant cursing you,

for you know that even you have cursed others many times as well.

I tested all this with wisdom, and I said, “I will be wise,” but wisdom was far from me.

What has been is remote and very mysterious. Who can discover it?

I directed my mind to know and to investigate, and to seek wisdom and an explanation, and to know the evil of foolishness and the foolishness of insanity.
