Proverbs 30:10-12

¶Do not slander or malign a servant before his master [stay out of another’s personal life], Or he will curse you [for your interference], and you will be found guilty. ¶There is a generation (class of people) that curses its father And does not bless its mother. There is a generation (class of people) that is pure in its own eyes, Yet is not washed from its filthiness.
