Proverbs 30:10-14 ESV
Do not slander a servant to his master,
lest he curse you, and you be held guilty.
There are those who curse their fathers
and do not bless their mothers.
There are those who are clean in their own eyes
but are not washed of their filth.
There are those—how lofty are their eyes,
how high their eyelids lift!
There are those whose teeth are swords,
whose fangs are knives,
to devour the poor from off the earth,
the needy from among mankind.
