Chapter 20 of 30 in Sabbath — 14 halachot
Halacha 1א׳
אָסוּר לְהוֹצִיא מַשָּׂא עַל הַבְּהֵמָה בְּשַׁבָּת שֶׁנֶּאֱמַר (שמות כג יב) "לְמַעַן יָנוּחַ שׁוֹרְךָ וַחֲמֹרֶךָ" וְכָל בְּהֶמְתֶּךָ. אֶחָד שׁוֹר וַחֲמוֹר וְאֶחָד כָּל בְּהֵמָה חַיָּה וָעוֹף. וְאִם הוֹצִיא עַל הַבְּהֵמָה אַף עַל פִּי שֶׁהוּא מְצֻוֶּה עַל שְׁבִיתָתָהּ אֵינוֹ לוֹקֶה לְפִי שֶׁאִסּוּרוֹ בָּא מִכְּלַל עֲשֵׂה. לְפִיכָךְ הַמְחַמֵּר אַחַר בְּהֶמְתּוֹ בְּשַׁבָּת וְהָיָה עָלֶיהָ מַשּׂאוֹי פָּטוּר:
It is forbidden to transport a load upon a beast on Shabbat; as it is stated (Exodus 23:12), "in order that your ox and your donkey (and all your animals) rest." It is the same whether it is an ox or a donkey or whether it is any beast, animal or fowl. But if he did transport [a load] on a beast—even though he is commanded about its rest—he is not lashed; as its prohibition [only] comes from the inference of a positive commandment. Hence one who drives behind his beast while it had a load upon it on Shabbat is exempt
Halacha 2ב׳
וַהֲלֹא לָאו מְפֹרָשׁ בַּתּוֹרָה שֶׁנֶּאֱמַר (שמות כ י) "לֹא תַעֲשֶׂה כָל מְלָאכָה אַתָּה וּבִנְךָ וּבִתֶּךָ וְעַבְדְּךָ וַאֲמָתֶךָ וּבְהֶמְתֶּךָ", שֶׁלֹּא יַחֲרשׁ בָּהּ וְכַיּוֹצֵא בַּחֲרִישָׁה. וְנִמְצָא לָאו שֶׁנִּתָּן לְאַזְהָרַת מִיתַת בֵּית דִּין וְאֵין לוֹקִין עָלָיו:
But is it not an explicit negative commandment in the Torah, as it is stated (Exodus 20:10), "you shall not do any work—you, your son or daughter, your slave or your maidservant, or your cattle?" This is that one should not plow with it and that which is similar to it; such that it comes out that it is a negative commandment that is given to a death penalty of the court—and we do not give lashes [in such a case].
Halacha 3ג׳
אָסוּר לְיִשְׂרָאֵל לְהַשְׁאִיל אוֹ לְהַשְׂכִּיר בְּהֵמָה גַּסָּה לְנָכְרִי שֶׁלֹּא יַעֲשֶׂה בָּהּ מְלָאכָה בְּשַׁבָּת וַהֲרֵי הוּא מְצֻוֶּה עַל שְׁבִיתַת בְּהֶמְתּוֹ. אָסְרוּ חֲכָמִים לִמְכֹּר בְּהֵמָה גַּסָּה לְנָכְרִי שֶׁמָּא יַשְׁאִיל אוֹ יַשְׂכִּיר. וְאִם מָכַר קוֹנְסִין אוֹתוֹ עַד עֲשָׂרָה בְּדָמֶיהָ וּמַחֲזִירָהּ. וַאֲפִלּוּ שְׁבוּרָה אֵין מוֹכְרִין. וּמֻתָּר לוֹ לִמְכֹּר לָהֶם עַל יְדֵי סַרְסוּר שֶׁהַסַּרְסוּר אֵינוֹ מַשְׂכִּיר וְאֵינוֹ מַשְׁאִיל:
It is forbidden for an Israelite to lend or rent his large livestock to a gentile, so that it not do work on Shabbat; as [the Israelite] is surely [still] commanded about its rest. The Sages forbade selling large livestock to a gentile, lest [the Israelite also] lend or rent [them to him]. And if he sold [it], we penalize him [to repurchase it at up to] ten times the price and bring it back. And we do not sell [it] even if it is broken. But it is permissible to sell to them through an agent, as an agent does not lend or rent.
