'Slander' in the Bible

The one who does not slander with his tongue, who does no evil to his neighbor, and who does not destroy his friend's reputation.

I have heard the slander of many; it is like terror all around me, as they conspire together and plot to take my life.

You sit and speak against your brother; you slander your own mother's son.

Whoever conceals hatred is a deceitful liar, and whoever spreads slander is a fool.
