If one shakes a sieve, refuse remains. So too do impurities cling to a man's reasoning. You will see how well a tree is cared for by its fruits; you will see how thankful a man's heart is by his speech. Birds will resort to their like; and truth will return to those who practice her. A man who fears God always speaks wisdom, but a fool is as changeable as the moon. A man of many oaths will make the hair stand upright, and where there is strife you have to stop your ears.
