Talmud Tractate: Berachot 9:5
חַיָּב אָדָם לְבָרֵךְ עַל הָרָעָה כְּשֵׁם שֶׁהוּא מְבָרֵךְ עַל הַטּוֹבָה, שֶׁנֶּאֱמַר (דברים ו) וְאָהַבְתָּ אֵת יְיָ אֱלֹהֶיךָ בְּכָל לְבָבְךָ וּבְכָל נַפְשְׁךָ וּבְכָל מְאֹדֶךָ. בְּכָל לְבָבְךָ, בִּשְׁנֵי יְצָרֶיךָ, בְּיֵצֶר טוֹב וּבְיֵצֶר רָע. וּבְכָל נַפְשְׁךָ, אֲפִלּוּ הוּא נוֹטֵל אֶת נַפְשֶׁךָ. וּבְכָל מְאֹדֶךָ, בְּכָל מָמוֹנֶךָ. דָּבָר אַחֵר בְּכָל מְאֹדֶךָ, בְּכָל מִדָּה וּמִדָּה שֶׁהוּא מוֹדֵד לְךָ הֱוֵי מוֹדֶה לוֹ בִּמְאֹד מְאֹד. לֹא יָקֵל אָדָם אֶת רֹאשׁוֹ כְּנֶגֶד שַׁעַר הַמִּזְרָח, שֶׁהוּא מְכֻוָּן כְּנֶגֶד בֵּית קָדְשֵׁי הַקָּדָשִׁים. לֹא יִכָּנֵס לְהַר הַבַּיִת בְּמַקְלוֹ, וּבְמִנְעָלוֹ, וּבְפֻנְדָּתוֹ, וּבְאָבָק שֶׁעַל רַגְלָיו, וְלֹא יַעֲשֶׂנּוּ קַפַּנְדַּרְיָא, וּרְקִיקָה מִקַּל וָחֹמֶר. כָּל חוֹתְמֵי בְרָכוֹת שֶׁהָיוּ בַמִּקְדָּשׁ, הָיוּ אוֹמְרִים מִן הָעוֹלָם. מִשֶּׁקִּלְקְלוּ הַמִּינִין, וְאָמְרוּ, אֵין עוֹלָם אֶלָּא אֶחָד, הִתְקִינוּ שֶׁיְּהוּ אוֹמְרִים, מִן הָעוֹלָם וְעַד הָעוֹלָם. וְהִתְקִינוּ, שֶׁיְּהֵא אָדָם שׁוֹאֵל אֶת שְׁלוֹם חֲבֵרוֹ בַּשֵּׁם, שֶׁנֶּאֱמַר (רות ב) וְהִנֵּה בֹעַז בָּא מִבֵּית לֶחֶם, וַיֹּאמֶר לַקּוֹצְרִים יְיָ עִמָּכֶם, וַיֹּאמְרוּ לוֹ, יְבָרֶכְךָ יְיָ. וְאוֹמֵר (שופטים ו) יְיָ עִמְּךָ גִּבּוֹר הֶחָיִל. וְאוֹמֵר (משלי כג) אַל תָּבוּז כִּי זָקְנָה אִמֶּךָ. וְאוֹמֵר (תהלים קיט) עֵת לַעֲשׂוֹת לַייָ הֵפֵרוּ תוֹרָתֶךָ. רַבִּי נָתָן אוֹמֵר, הֵפֵרוּ תוֹרָתֶךָ עֵת לַעֲשׂוֹת לַייָ:
One must bless [God] for the evil in the same way as one blesses for the good, as it says, “And you shall love Adonai your God with all your heart, with all your soul and with all your might” (Deuteronomy 6:5). “With all your heart,” with your two impulses, the evil impulse as well as the good impulse. “With all your soul” even though God takes your soul [life] away from you. “With all your might” with all your money. Another explanation, “With all your might” whatever treatment God metes out to you. One should not show disrespect to the Eastern Gate, because it is in a direct line with the Holy of Holies. One should not enter the Temple Mount with a staff, or with shoes on, or with a wallet, or with dusty feet; nor should one make it a short cut, all the more spitting [is forbidden]. All the conclusions of blessings that were in the Temple they would say, “forever [lit. as long as the world is].” When the sectarians perverted their ways and said that there was only one world, they decreed that they should say, “for ever and ever [lit. from the end of the world to the end of the world]. They also decreed that a person should greet one’s fellow in God’s name, as it says, “And behold Boaz came from Bethlehem and said to the reapers, ‘May Adonai be with you.’ And they answered him, “May Adonai bless you’” (Ruth 2:4). And it also says, “Adonai is with your, you valiant warrior” (Judges 6:12). And it also says, “And do not despise your mother when she grows old” (Proverbs 23:22). And it also says, “It is time to act on behalf of Adonai, for they have violated Your teaching” (Psalms 119:126). Rabbi Natan says: [this means] “They have violated your teaching It is time to act on behalf of Adonai.”
