Chapter 29
Laws Derived from Isaiah: Running, Walking, Commerce, Measuring, Reading, Speaking
SPEAKING ON SHARBATH AND YOM TOV WITH THE OBJECT OF CONDUCTING EVERYDAY AFFAIRS
51.a. One must not on Shabbath tell another person, even a non-Jew, to do something for one after Shabbath if
1) it is forbidden to do that thing on Shabbath itself and
2) there is no possibility of doing it in a permitted manner on Shabbath.
51.b. Making such a request would amount to pursuing one’s business on Shabbath by means of one’s words, contrary to the prohibition based on the verses in Isaiah referred to in paragraph 2 above.
51.c. As mentioned there, and as will become clearer in the ensuing paragraphs, pursuing one’s own business is forbidden, but pursuing the business of Heaven in permitted.
