Ecclesiastes 7:21-25

²¹Also don’t take heed to all words that are spoken, lest you hear your servant curse you;

²²for often your own heart knows that you yourself have likewise cursed others.

²³All this I have proved in wisdom. I said, “I will be wise;” but it was far from me.

²⁴That which is, is far off and exceedingly deep. Who can find it out?

²⁵I turned around, and my heart sought to know and to search out, and to seek wisdom and the scheme of things, and to know that wickedness is stupidity, and that foolishness is madness.
