The
Jerusalem Talmud mentions that the first dispute in Israel concerned the laying on of hands (
semicha) upon the head of one's sacrificial animal during a Festival Day, with applied force, some permitting the owner of the animal to do so, others forbidding him to do so. The
Babylonian Talmud provides a more detailed set of regulations for the practice of
semicha. :How does one lean [perform
semicha]? The offering stands in the north, with its face towards the west, and the one who leans stands in the east, with his face to the west. And he places his two hands between the two horns of the offering; however, there may be nothing interposing between his [bare] hands and the offering; and he confesses over a
chatat [sin-offering] the sins of a
chatat, and over an
asham [guilt-offering] the sins of an
asham. and over an
olah (burnt-offering) [...the sins of an
olah]. The
Mishnah and
Talmud record a debate on whether
semicha may be performed on Jewish holidays, as it is considered a form of labor by the animal (supporting the owner's weight) which would normally be forbidden on holidays. Women who offer sacrifices are allowed to perform
semicha, but not required to. This ruling is extensively debated in later sources, as it involves the questions of whether this
semicha fulfilled the commandment or else was done purely to gratify the women without having ritual significance; whether performing a commandment in a situation where it does not apply violates the prohibition of
bal tosif; how a "commandment" can exist if its performance is not required; whether a blessing can be recited on such an optional "commandment"; and so on. The results of this discussion are highly relevant to other commandments which are required for men and optional for women, such as
lulav and
shofar. == Interpretations ==
