'Slanderer' in the Bible

Let not the slanderer become established in the land. May evil quickly hunt down the violent man.

"Beware of your neighbors, and don't trust any of your relatives. For all of your relatives act deceitfully, and every friend goes around as a slanderer.

But now I am writing to you to stop associating with any so-called brother if he is sexually immoral, greedy, an idolater, a slanderer, a drunk, or a robber. You must even stop eating with someone like that.
