Proverbs 20:9-11

New Revised Standard Version, Anglicised Catholic Edition

⁹ Who can say, ‘I have made my heart clean;
    I am pure from my sin’?
¹⁰ Diverse weights and diverse measures
    are both alike an abomination to the Lord.
¹¹ Even children make themselves known by their acts,
    by whether what they do is pure and right.
