All the ways of a man are pure in his own eyes, And Jehovah is pondering the spirits.

Even by his actions a youth maketh himself known, Whether his work be pure or upright.

Froward is the way of a man who is vile, And the pure -- upright is his work.

A ring of gold, and an ornament of pure gold, Is the wise reprover to an attentive ear.

A generation -- pure in their own eyes, But from their own filth not washed.
