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?
