Ecclesiastes 7:23 in the King James Version
All this have I proved by wisdom: I said, I will be wise; but it was far from me.
Context
22 for often your own heart knows that you yourself have likewise cursed others.
23 All this I have proved in wisdom. I said, “I will be wise;” but it was far from me.
24 That which is, is far off and exceedingly deep. Who can find it out?
