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

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

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