Sirach 27:3-5

New Revised Standard Version, Anglicised

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

⁴ When a sieve is shaken, the refuse appears;
    so do a person’s faults when he speaks.
⁵ The kiln tests the potter’s vessels;
    so the test of a person is in his conversation.
