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).
what is the meaning of Kadosh ?
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.
