Proverbs 20:9-11

⁹Who may say, Mine heart is clean; I am clean of sin?

¹⁰A weight, greater in buying, and a weight, less (er) in selling, a measure and a measure, ever either is abominable at God (or these be abominable to God).

¹¹A child is understood by his studies (or Even a child is known by his deeds), if his works be rightful and clean.
