young adults shiur
Young adults face many challenges but one way they can over come them is reminding themselves what they here to do in life and that the best way to overcome any challenges in life is to subjugate ourselves to Hashem and follow His Torah

הוּא הָיָה אוֹמֵר, בֶּן חָמֵשׁ שָׁנִים לַמִּקְרָא, בֶּן עֶשֶׂר לַמִּשְׁנָה, בֶּן שְׁלשׁ עֶשְׂרֵה לַמִּצְוֹת, בֶּן חֲמֵשׁ עֶשְׂרֵה לַתַּלְמוּד, בֶּן שְׁמֹנֶה עֶשְׂרֵה לַחֻפָּה, בֶּן עֶשְׂרִים לִרְדֹּף, בֶּן שְׁלשִׁים לַכֹּחַ, בֶּן אַרְבָּעִים לַבִּינָה, בֶּן חֲמִשִּׁים לָעֵצָה, בֶּן שִׁשִּׁים לַזִּקְנָה, בֶּן שִׁבְעִים לַשֵּׂיבָה, בֶּן שְׁמֹנִים לַגְּבוּרָה, בֶּן תִּשְׁעִים לָשׁוּחַ, בֶּן מֵאָה כְּאִלּוּ מֵת וְעָבַר וּבָטֵל מִן הָעוֹלָם:

He used to say:
At five years of age the study of Scripture;
At ten the study of Mishnah;
At thirteen subject to the commandments;
At fifteen the study of Talmud;
At eighteen the bridal canopy;
At twenty for pursuit [of livelihood];
At thirty the peak of strength;
At forty wisdom;
At fifty able to give counsel;
At sixty old age;
At seventy fullness of years;
At eighty the age of “strength”;
At ninety a bent body;
At one hundred, as good as dead and gone completely out of the world.

This mishnah gives ages that are appropriate for the different stages in life. We should note that in most places in the Mishnah, the age at which a child is obligated or allowed to do something is dependent not on his true age but either on his/her physical or mental development. Indeed this mishnah, which lists true ages, is probably more of a guide and not to meant to be legally binding. The Meiri states that it is meant as a stimulus to parents to teach their children the right subject at the right time. In modern times we also give rough ages of development but realize that some children will be quicker to reach those milestones and some will be slower.
Although this mishnah begins “he used to say” and therefore seems to be Judah ben Tema’s words, according to the Tosafot Yom Tov it is actually the words of Shmuel Hakatan.

At twenty for pursuit [of livelihood]: Once he has married a woman and had a child or two, he must pursue means to support his family. By twenty a person should have a profession. Others interpret this to mean that at twenty a person stops learning Torah and begins to work. Still others interpret this to mean that at twenty he pursues the enemy in war. This is the age at which one is liable to join the army, according to the Torah (Numbers 1:3).
At thirty the peak of strength: At thirty a person is at the peak of his strength. In the Torah the Levites only begin to work in the Tabernacle at thirty (see Numbers 4:47).

מִבֶּ֨ן עֶשְׂרִ֤ים שָׁנָה֙ וָמַ֔עְלָה כׇּל־יֹצֵ֥א צָבָ֖א בְּיִשְׂרָאֵ֑ל תִּפְקְד֥וּ אֹתָ֛ם לְצִבְאֹתָ֖ם אַתָּ֥ה וְאַהֲרֹֽן׃
You and Aaron shall record them by their groups, from the age of twenty years up, all those in Israel who are able to bear arms.
וְאַתֶּ֧ם תִּהְיוּ־לִ֛י מַמְלֶ֥כֶת כֹּהֲנִ֖ים וְג֣וֹי קָד֑וֹשׁ אֵ֚לֶּה הַדְּבָרִ֔ים אֲשֶׁ֥ר תְּדַבֵּ֖ר אֶל־בְּנֵ֥י יִשְׂרָאֵֽל׃
but you shall be to Me a kingdom of priests and a holy nation.’ These are the words that you shall speak to the children of Israel.”

what is the meaning of Kadosh ?

ואלה המשפטים. כָּל מָקוֹם שֶׁנֶּאֱמַר "אֵלֶּה" פָּסַל אֶת הָרִאשׁוֹנִים, "וְאֵלֶּה" מוֹסִיף עַל הָרִאשׁוֹנִים, מָה הָרִאשׁוֹנִים מִסִּינַי, אַף אֵלּוּ מִסִּינַי; וְלָמָּה נִסְמְכָה פָּרָשַׁת דִּינִין לְפָרָשַׁת מִזְבֵּחַ? לוֹמַר לְךָ, שֶׁתָּשִׂים סַנְהֶדְרִין אֵצֶל הַמִּקְדָּשׁ (מכילתא):
ואלה המשפטים NOW THESE ARE THE JUDGMENTS — Wherever אלה, “these are”, is used it cuts off (פוסל) the preceding section from that which it introduces; where, however, ואלה “and these” is used it adds something to the former subject (i. e. forms a continuation of it). So also here: “And these are the judgments (i. e. these, also)”: What is the case with the former commandments (the עשרת הדברות)? They were given at Sinai! So these, too, were given at Sinai! (Mekhilta d'Rabbi Yishmael 21:1:1; Shemot Rabbah 30:3; cf. also Midrash Tanchuma, Mishpatim 3) If this be so, why is this section dealing with the “civil laws” placed immediately after that commanding the making of the altar? To tell you that you should seat (i. e. provide quarters for) the Sanhedrin in the vicinity of the Temple.
אָֽנֹכִ֖י֙ יְהֹוָ֣ה אֱלֹהֶ֑֔יךָ אֲשֶׁ֧ר הוֹצֵאתִ֛יךָ מֵאֶ֥רֶץ מִצְרַ֖יִם מִבֵּ֣֥ית עֲבָדִ֑͏ֽים׃
I יהוה am your God who brought you out of the land of Egypt, the house of bondage:
מִצְוָה רִאשׁוֹנָה מִמִּצְווֹת עֲשֵׂה, לֵידַע שֶׁיֵּשׁ שָׁם אֱלוֹהַּ, שֶׁנֶּאֱמָר: "אָנֹכִי ה' אֱלֹהֶיךָ" (שמות כ ב, דברים ה ו).
The first of the positive commandments is the mitzvah to know that there is a God, as [Exodus 20:2] states: "I am God, your Lord."

וְרַבִּי אָלֶכְּסַנְדְרִי בָּתַר דִּמְצַלֵּי אָמַר הָכִי: ״רִבּוֹן הָעוֹלָמִים, גָּלוּי וְיָדוּעַ לְפָנֶיךָ שֶׁרְצוֹנֵנוּ לַעֲשׂוֹת רְצוֹנֶךָ, וּמִי מְעַכֵּב? — שְׂאוֹר שֶׁבָּעִיסָּה וְשִׁעְבּוּד מַלְכֻיוֹת. יְהִי רָצוֹן מִלְּפָנֶיךָ שֶׁתַּצִּילֵנוּ מִיָּדָם, וְנָשׁוּב לַעֲשׂוֹת חוּקֵּי רְצוֹנְךָ בְּלֵבָב שָׁלֵם״.


Some say that this was the prayer that Rav Hamnuna would recite, and that after Rabbi Alexandri prayed, he would say the following:
Master of the Universe, it is revealed and known before You
that our will is to perform Your will, and what prevents us?
On the one hand, the yeast in the dough, the evil inclination that is within every person;
and the subjugation to the kingdoms on the other.
May it be Your will
that You will deliver us from their hands, of both the evil inclination and the foreign kingdoms,
so that we may return to perform the edicts of Your will with a perfect heart.

וְאוֹמֵר (שמות לב) וְהַלֻּחֹת מַעֲשֵׂה אֱלֹהִים הֵמָּה וְהַמִּכְתָּב מִכְתַּב אֱלֹהִים הוּא חָרוּת עַל הַלֻּחֹת, אַל תִּקְרָא חָרוּת אֶלָּא חֵרוּת, שֶׁאֵין לְךָ בֶן חוֹרִין אֶלָּא מִי שֶׁעוֹסֵק בְּתַלְמוּד תּוֹרָה.

And it says, “And the tablets were the work of God, and the writing was the writing of God, graven upon the tablets” (Exodus 32:16). Read not haruth [‘graven’] but heruth [ ‘freedom’]. For there is no free man but one that occupies himself with the study of the Torah.

וַיִּקַּח֙ סֵ֣פֶר הַבְּרִ֔ית וַיִּקְרָ֖א בְּאׇזְנֵ֣י הָעָ֑ם וַיֹּ֣אמְר֔וּ כֹּ֛ל אֲשֶׁר־דִּבֶּ֥ר יְהֹוָ֖ה נַעֲשֶׂ֥ה וְנִשְׁמָֽע׃
Then he took the record of the covenant and read it aloud to the people. And they said, “All that יהוה has spoken we will faithfully do!”
כָּךְ הַקָּדוֹשׁ בָּרוּךְ הוּא אָמַר לָהֶם לְיִשְׂרָאֵל בָּנַי בָּרָאתִי יֵצֶר הָרָע וּבָרָאתִי לוֹ תּוֹרָה תַּבְלִין וְאִם אַתֶּם עוֹסְקִים בַּתּוֹרָה אֵין אַתֶּם נִמְסָרִים בְּיָדוֹ שֶׁנֶּאֱמַר הֲלוֹא אִם תֵּיטִיב שְׂאֵת
So too the Holy One, Blessed be He, said to Israel: My children, I created an evil inclination, which is the wound, and I created Torah as its antidote. If you are engaged in Torah study you will not be given over into the hand of the evil inclination, as it is stated: “If you do well, shall it not be lifted up?” (Genesis 4:7). One who engages in Torah study lifts himself above the evil inclination.
