Scriptural source The name "
Tashlikh" and the practice itself are derived from an
allusion mentioned in the
Biblical passage () recited at the ceremony: "You will cast (
tashlikh) all their sins into the depths of the sea."
Possible early sources •
Josephus () refers to the decree of the
Halicarnassians permitting Jews to "perform their holy rites according to the Jewish laws and to have their places of prayer by the sea, according to the customs of their forefathers". However, there was an ancient Jewish custom to site
synagogues of the
Jewish diaspora on the seashore as an expression of desire to
return to Zion. • The
Zohar () states that "whatever falls into the deep is lost forever; ... it acts like the
scapegoat for the
ablution of
sins". Some believe that this is a reference to the
tashlikh ritual.
Maharil Most Jewish sources trace the custom back to
Yaakov ben Moshe Levi Moelin (d. 1427 in
Worms) in his
Sefer Maharil, where he explains the custom as a reminder of the
binding of Isaac, and the general impression has therefore been that it originated not earlier than the fourteenth century, with the German Jews. Moelin, however, forbids the practise of throwing pieces of bread to the fish in the river, especially on
Shabbat. This would seem to indicate that in his time
tashlikh was duly performed, even when the first day of Rosh Hashanah fell on the Sabbath, though in later times the ceremony was, on such occasions, deferred one day. The deeps of the sea allude to the existence of a single Creator that created the world and that controls the world by, for example, not letting the seas
flood the earth. Thus, we go to the sea and reflect upon that on
New-Year's Day, the anniversary of Creation. We reflect upon proof of the Creator's creation and of His control, so as to repent of our sins to the Creator, and so he will figuratively "cast our sins into the depths of the sea" (). ==Opposition to the custom==
