Rabbi Yochanan, in the name of Yossi, the son of Zimra, asks, "What is
this that is written (Ps. cxx. 3), 'What shall be given unto thee, or
what shall be added unto thee, O thou false tongue'?" The Holy
One--blessed be He!--said to the tongue, "All the members of the body
are erect, thou only art recumbent; all other members are without, thou
art within, and not only so, for I have surrounded thee with two walls,
one of bone and the other of flesh. What shall be given to thee, or what
shall be added unto thee, O thou false tongue?" Rabbi Yochanan, in the
name of Yossi, says, "He who slanders is an atheist, for it is written
(Ps. xii. 4), 'Who have said, With our tongues will we prevail; Our lips
are with us; who is lord over us?'"

All animals will one day remonstrate with the serpent and say, "The lion
treads upon his prey and devours it, the wolf tears and eats it, but
thou, what profit hast thou in biting?" The serpent will reply (Eccl.
viii. II), "I am no worse than a slanderer."
