Shabbat VS saving someones life
Tzedakah VS Shabbat
Helping the sick VS sitting in the Sukkah
Burying the dead VS Davenning on Yom Kippur
Our Sages have taught: If someone is overcome by ravenous hunger, we give him to eat [if only forbidden foods are on hand] that which is of comparatively minor import. [If he has before him] untithed produce and the meat of an improperly slaughtered animal – we give him to eat the meat of the improperly slaughtered animal; untithed produce and sabbatical produce – [we give him] the sabbatical produce; untithed produce and teruma (produce set aside as a priestly gift), this is the subject of a Tannaitic dispute…
(א) רַבִּי אוֹמֵר, אֵיזוֹהִי דֶרֶךְ יְשָׁרָה שֶׁיָּבֹר לוֹ הָאָדָם, כֹּל שֶׁהִיא תִפְאֶרֶת לְעוֹשֶׂיהָ וְתִפְאֶרֶת לוֹ מִן הָאָדָם. וֶהֱוֵי זָהִיר בְּמִצְוָה קַלָּה כְבַחֲמוּרָה, שֶׁאֵין אַתָּה יוֹדֵעַ מַתַּן שְׂכָרָן שֶׁל מִצְוֹת. וֶהֱוֵי מְחַשֵּׁב הֶפְסֵד מִצְוָה כְּנֶגֶד שְׂכָרָהּ, וּשְׂכַר עֲבֵרָה כְנֶגֶד הֶפְסֵדָהּ. וְהִסְתַּכֵּל בִּשְׁלשָׁה דְבָרִים וְאִי אַתָּה בָא לִידֵי עֲבֵרָה, דַּע מַה לְּמַעְלָה מִמְּךָ, עַיִן רוֹאָה וְאֹזֶן שׁוֹמַעַת, וְכָל מַעֲשֶׂיךָ בַסֵּפֶר נִכְתָּבִין:
(1) Rabbi [Yehuda haNasi] said: Which is the straight path that a person should choose for himself? Whichever [path] that is [itself] praiseworthy for the person adopting [it], And praiseworthy to him from [other] people. And be as careful with a light commandment as with a weighty one, for you do not know the reward given [for the fulfillment] of [the respective] commandments. Also, weigh the loss [that may be sustained through the fulfillment] of a commandment against the reward [that may be obtained] for [fulfilling] it. And [weigh] the gain [that may be obtained through the committing] of a transgression against the loss [that may be sustained] by [committing] it. Keep your eye on three things, and you will not come to sin: Know what is above you: An Eye that sees, and an Ear that hears, and all your deeds are written in a book.
The Sages further declare: “Anyone who observes Shabbat properly, even if he worships foreign deities like the generation of Enosh (when paganism first emerged), is forgiven” (Shabbat 118b)
(ב) בֶּן עַזַּאי אוֹמֵר, הֱוֵי רָץ לְמִצְוָה קַלָּה כְבַחֲמוּרָה, וּבוֹרֵחַ מִן הָעֲבֵרָה. שֶׁמִּצְוָה גּוֹרֶרֶת מִצְוָה, וַעֲבֵרָה גוֹרֶרֶת עֲבֵרָה. שֶׁשְּׂכַר מִצְוָה, מִצְוָה. וּשְׂכַר עֲבֵרָה, עֲבֵרָה:
(2) Ben Azai says: Run to do an easy commandment as to a difficult one, and flee from sin; since a commandment leads to another commandment, and a sin leads to another sin; since the reward for a commandment is another commandment, and the reward for a sin is another sin.
