신명기 33:18 할라카: Mishneh Torah, Torah Study & Kitzur Shulchan Arukh

The words of the Torah do not remain permanently with one who is indolent in acquiring them, nor with such who study the Torah in an environment of luxury and amidst eating and drinking, but with one who sacrifices his life for them and constantly suffers his body and does not yield sleep to his eyes nor dozing to his eyelids. Said the wise men symbolically: "This is the Law, when a man dieth in a tent" (Num. 19.14); the Torah does not remain with any save with him who sacrifices his life in the tents of the wise. And so did Solomon in his wisdom say: "If thou fall in the day of adversity thy strength is small indeed" (Prov. 24.10); and he, moreover, said: "Also my wisdom stood me in stead¹²The word Aph in the Hebrew text is usually translated to mean “also”, also means wrath or trouble. G. (Ecc. 2.9); only the wisdom which I studied in trouble stood me in stead" (Shabbat, 83a). The sages said: "There is an established covenant that he who endures hardship in studying the Torah in the Beth Hamedrash will not easily forget it; but he who endures the hardship of his studies privately by himself becomes wise, even as it is said: "But with the lowly is wisdom" (Prov. 11.2). He who during his study reads the words audibly, his study remains with him; but he who whispers out his words speedily forgets them.¹³Ketubot, 111b; Berakot, 65a; Menahot, 54a; Yer. Berakot, 41. C. G.

Every Jewish man must study the Torah, no matter whether he is poor or rich, whether he is healthy or suffering pain, whether he is young or very old. Even a beggar who goes from door to door must set aside a certain time for Torah study during the day and night, as it is written:²Joshua 1:8. "And you shall meditate in it day and night." If a person lacks the knowledge to study Torah or it is impossible for him [to study] because he is burdened with too many concerns, then he should support others who do engage in Torah study, and it will be considered as though he himself had studied, as our Rabbis of blessed memory, explained the verse: "Rejoice Zevulun in your going out and Yissachar in your tents."³Deuteronomy 33:18. Zevulun and Yissachar entered into a partnership; Zevulun engaged in business and supported Yissachar, so that he would be free to be engrossed in the study of Torah. Because of this, the Torah mentions Zevulun before Yissachar, since the Torah learning of Yissachar was made possible through the support of Zevulun. And so we find in the Mishnah: "Shimon the brother of Azaryah said …,"⁴Zevachim 1:2. Shimon is described as the brother of Azaryah, because Azaryah was engaged in business and provided the needs of his brother Shimon, who was engrossed in Torah study. They made an agreement between themselves, that Azaryah would have a share in Shimon's reward for [Torah] study. Even so, every person should do his utmost to study Torah, even just a little, every day and every night.
