Ecclesiastes 7:21

Also take no heed unto all words that are spoken; lest thou hear thy servant curse thee:
19

Wisdom strengtheneth the wise more than ten mighty men which are in the city.

20

For there is not a just man upon earth, that doeth good, and sinneth not.

21

Also take no heed unto all words that are spoken; lest thou hear thy servant curse thee:

22

For oftentimes also thine own heart knoweth that thou thyself likewise hast cursed others.

23

All this have I proved by wisdom: I said, I will be wise; but it was far from me.
