Proverbs 30:10-12

Young's Literal Translation

¹⁰ Accuse not a servant unto his lord, Lest he disesteem thee, and thou be found guilty.

¹¹ A generation [is], that lightly esteemeth their father, And their mother doth not bless.

¹² A generation -- pure in their own eyes, But from their own filth not washed.
