'Slanderer' in the Bible

The words of a whisperer (gossip) are like dainty morsels [to be greedily eaten];They go down into the innermost chambers of the body [to be remembered and mused upon].

If the serpent bites before being charmed, then there is no profit for the charmer.

“Let everyone beware of his neighborAnd do not trust any brother.For every brother is a supplanter [like Jacob, a deceiver, ready to grab his brother’s heel],And every neighbor goes around as a slanderer.
