30:10–14 Speak no slander—not even against the wicked who curse their fathers and neglect their mothers; who believe themselves to be so pure that they fail to cleanse their hearts; whose eyes blaze with disdain and whose brows arch with ridicule; whose teeth are swords and knives devouring the land of the poor and depriving the destitute of sanctuary. For so poisonous is slander that in the end it is you that is called wicked.5
