Sirach 27:3-5

Revised Standard Version

³ If a man is not steadfast and zealous in the fear of the Lord,
    his house will be quickly overthrown.

⁴ When a sieve is shaken, the refuse remains;
    so a man’s filth remains in his thoughts.
⁵ The kiln tests the potter’s vessels;
    so the test of a man is in his reasoning.
