Proverbs 30:10-12

Lexham English Bible

¹⁰ Do not slander a servant to his master,
    or else he will curse you and you will be guilty.
¹¹ There is a generation that will curse its father,
    and its mother it will not bless.
¹² There is a generation that is pure in its own eyes,
    but from its filthiness it will not be cleansed.
