Chapter 82:3
Carrying from One Domain to Another
3. Lifting an article from its resting position is called "akirah";
placing it down is called "hanacha." [Not only is it forbidden for a person
to perform the "akirah" in one domain and then the "hanacha" in a different
domain], but it is also forbidden to perform the "akirah" [in one domain],
without [being the one to perform] the "hanachah" [in a different domain],
or to perform the "hanacha" and not the "akirah" (1).
Accordingly, it is forbidden for a Jew [to pick up an object in a "reshus
ha'yochid" (private domain)], and hand it to a Gentile to take out of the
private domain into the public domain or into a "carmelis," because [by
picking it up and handing it to him] the Jew is performing the '"akirah."
Instead, the gentile should pick it up [in the private domain]
himself. Likewise, when a Gentile brings an article [from a different
domain], a Jew should not take it from him, because the Jew would then be
performing a "hanacha." Rather, the Gentile should place the article down
himself.
[This concept is particularly relevant when a child's circumcision takes
place on Shabbos, and] the infant is brought [from his home] to the
synagogue by a Gentile women; the Gentile should pick up the baby herself
in the house and, upon arrival at the synagogue, place him down in the
courtyard or foyer. A Jew may then pick up [the baby] (2).
FOOTNOTES:
(1) Most authorities agree that the prohibition against performing only the
"akira" or only the "hanacha" is a rabbinical enactment.
(2) The Mishnah Berurah 331:20 maintains that one should have the child
circumcised at home, rather than have a Gentile bring him to the synagogue.
