In continuation of the above we read that Shemuel said to Rav
Yehudah, "Shrewd fellow, open thy mouth when thou readest, etc.,
so that thy reading may remain and thy life may be lengthened;
as it is written in Prov. iv. 22, 'For they are life unto those
that find them;' read not, 'that find them,' but read, 'that
bring them forth by the mouth,' i.e., that read them aloud." It
was and is still a common custom in the East to study aloud.
As an anathema enters all the two hundred and forty-eight members of the
body, so does it issue from them all. Of the entering-in of the anathema
it is written (Josh. vi. 17), "And the city shall be accursed;" by
Gematria amounting to two hundred and forty-eight. Of the coming-out of
the anathema it is written (Hab. iii. 2), "In wrath remember mercy;" a
transposition of the letters of the word for accursed, also amounting by
Gematria to two hundred and forty-eight. Rabbi Joseph says, "Hang an
anathema on the tail of a dog and he will still go on doing mischief."
