'Slanders' in the Bible

I will silence whoever secretly slanders his neighbor. I won't tolerate one who is haughty and conceited.

They are all grievous rebels, going about with slanders; they are brass and iron: they all of them deal corruptly.

Take heed everyone of his neighbor, and don't trust in any brother; for every brother will utterly supplant, and every neighbor will go about with slanders.
