'Slander' in the Bible

through glory and dishonor,through slander and good report;as deceivers yet true;

For I fear that perhaps when I come I will not find you to be what I want, and I may not be found by you to be what you want; there may be quarreling, jealousy, outbursts of anger, selfish ambitions, slander, gossip, arrogance, and disorder.
