Proverbs 30:10-14

“Do not slander a servant to their master, or they will curse you, and you will pay for it. “There are those who curse their fathers and do not bless their mothers; those who are pure in their own eyes and yet are not cleansed of their filth; those whose eyes are ever so haughty, whose glances are so disdainful; those whose teeth are swords and whose jaws are set with knives to devour the poor from the earth and the needy from among mankind.
