20For no man is so righteous upon earth, that he should do always good, and never sin.—
21Also take no heed unto all the words that are spoken: lest thou hear thy servant cursing thee.
22For oftentimes also doth thy own heart know that thou thyself likewise hast cursed others.—
23All this have I proved by wisdom: I said, I will be wise; but it was far from me.
24Far is what formerly was so, and what was deep remaineth deep: who can find it out?
