At the close of the Sabbath he is to pronounce over a cup of wine what
is technically termed the "Separation," for the departure of the
Sabbath, as given in the prayer-book. He is then to fold up his Tallith
or veil and sing "Hamavdil," the first verse of which runs thus:--
"May He who maketh a distinction between the holy (Sabbath) and the
profane (days of the week) pardon our sins and multiply our children and
our money as the sand and as the stars in the night!"
Should he forget to fold his veil (Tallith), he is to shake it
thoroughly the next morning, in order to get rid of the evil spirits
that have harbored there during the night, and the reason is known to
the lords of the Kabbalah.
