From the fruit of his lips a man enjoys good things.
Anxiety in a man's heart weighs him down, but a good word makes him glad.
As iron sharpens iron, so a friend sharpens a friend.
All the rivers run into the sea; yet the sea is not full.
To gain riches is wise; to pay for riches with happiness is foolish.
He mocks proud mockers but gives grace to the humble. from the Book of Proverbs
