Proverbs 30:10-12

Evangelical Heritage Version

¹⁰ Do not slander a servant to his master.
If you do, he will curse you,
and you will be found guilty.
¹¹ There is a type of person who curses his father
and does not bless his mother.
¹² This person is pure in his own eyes,
but he is not washed from his filth.
