LEV538 We are forbidden to speak against others. This is the prohibition dealing specifically with loshon hara and r'chilus. Loshon hara is the term used for a derogatory or damaging statement about someone. R'chilus is the term used for a report that someone has spoken or acted against the listener. For example, you tell Reuven that Shimon said he is lazy. [Transcriber's note: Author provides extensive discussion of laws with many illustrative examples].
