Midrash su Deuteronomio 14:26

One time I was walking on the way. A man found me, and went with me on the way of mitzvot, and he had mikra (ie: written law) but no mishnah (ie: oral law). And he said to me, "Rabbi, mikra was given to us from Mount Sinai. Mishnah was not given to us from Mount Sinai." And I said to him, "My son, mikra and mishnah were both of them said from the mouth of God." And what is the difference between mikra and mishnah? Rather he told him a parable: To what is this matter similar? To a human king (lit: a king of flesh and blood) who had two servants, and he loved them with a great love. And he gave to one a kab (a measure) of wheat and to the other kab of wheat. And he also gave to each one of them a bundle of flax. The wise one of them took the flax and wove a beautiful cloth, and took the wheat and made it into fine flour, and sifted it, and ground it, and kneaded it, and baked it, and set it on the table, and spread the beautiful cloth over it, and left it there until the king should come. And the fool of them did nothing. After some time the king came into his house, and said to them, to his two servants, "My sons, bring to me what I gave you." One of them brought out the bread of fine flour, on the table, with the beautiful cloth spread over it. And the other of them brought out the wheat in a pile and the bundle of flax upon it. Woe for that shame! Woe for that disgrace! Which one is more favored? You must admit it is the one who brought out the bread on the table with the beautiful cloth spread over it.

R. Tanchum said in the name of R. Chanilai: "Every Judaean who has no wife lives without happiness, without blessing, and without good; without happiness, as it is written (Deut. 14, 26) And thou shalt rejoice, thou and thy household; without blessing, as it is written (Ez. 44, 30) To cause a blessing to rest on thy house; without good, as it is written (Ben. 2, 18) It is not good that the man should be alone." In Palestine it was said: "He [who is unmarried] is without Torah and without protection; i.e., without Torah, as it is written (Job 6, 13) Truly, am I not without my help in me, and is not Tushiya driven far away from me? Without protection, as it is written (Jer. 31, 21) The woman will go about [to protect] the husband." Raba b. Ulla said: "Also without peace, as it is written (Job 5, 24) And thou shalt know that there is peace in thy tent," etc.

“Enjoy life with a woman whom you love all the days of your life of vanity which He has given you under the sun, all the days of your vanity, as that is your portion in life, and in your toil that you toil under the sun” (Ecclesiastes 9:9).
“Enjoy life with a woman whom you love.” Rabbi [Yehuda HaNasi] said in the name of the holy congregation: Acquire for yourself a craft with Torah. What is the reason? “Enjoy life [with a woman]…”²⁷The midrash is interpreting the world “life” to refer to Torah, and the term “woman” to refer to a craft. One should have a craft with which to earn a livelihood, in addition to studying Torah. Why does he call them the holy congregation? It is because Rabbi Yosei ben Meshulam and Rabbi Shimon ben Menaseya, who would divide the day into three, one-third for Torah, one-third for prayer, and one-third for labor, were there. Some say: They would engage in Torah study during the days of winter, and in labor during the days of summer. Rabbi Yitzḥak ben Elazar would call Rabbi Yehoshua son of Rabbi Timi and Rabbi Burki the holy congregation, because they would divide the day into three, one-third for Torah, one-third for prayer, and one-third for labor.
It is taught: It is prohibited for a mourner to marry a woman until thirty days [pass]. Rabbi Yehuda says: Until three consecutive pilgrimage festivals pass, corresponding to the three times that it is written: Life, life, life. In what case is this said? In a case when he has sons; however, if he has no sons, or if he has minor sons, it is permitted due to diminution of procreation and to see to their needs.²⁸The mourner can marry a woman even within thirty days in order to fulfill the mitzva of procreation, or so that his new wife can take care of his young children. There was an incident and the wife of Rabbi Tarfon died, and when the grave was covered, he said to her sister amidst the mourning: ‘Enter my house²⁹Marry me. and raise your sister’s children.’ Even though he married her, he did not engage in conjugal relations until after thirty days. It is taught: It is prohibited for a mourner to go to a house of feasting until thirty days [have passed].
It was taught: The mitzvot incumbent upon a father regarding his son are to circumcise him and to redeem him, and also to teach him Torah, to teach him a trade, and to marry him to a woman. Some say: Also to teach him to swim in a river. To circumcise him, from where [is it derived]? As it is stated: “He that is eight days old shall be circumcised among you, every male” (Genesis 17:12). To redeem him, from where [is it derived]? As it is stated: “And all the first-born of man among your sons you shall redeem” (Exodus 13:13). To teach him Torah, from where [is it derived]? As it is stated: “You shall teach them” (Deuteronomy 11:19). To marry a woman, from where [is it derived]? As it is stated: “Take women and beget sons and daughters and take women for your sons” (Jeremiah 29:6). To teach him to swim in a river, from where [is it derived]? As it is stated: “You shall choose life” (Deuteronomy 30:19).
Anyone who does not have a wife is without goodness, without a helper, without joy, without blessing, without atonement. Without good, from where [is it derived]? [From the verse:] “It is not good for man to be alone” (Genesis 2:18). Without help, from where [is it derived]? [From the verse:] “I will make him a helper alongside him” (Genesis 2:18). Without joy, from where [is it derived]? [From the verse:] “You shall rejoice, you and your household” (Deuteronomy 14:26). Without blessing, from where [is it derived]? [From the verse:] “To place a blessing upon your house” (Ezekiel 44:30). Without atonement, from where [is it derived]? [From the verse:] “And he shall atone for himself and for his household” (Leviticus 16:11). Rabbi Yehoshua ben Levi says: Without life as well, as it is stated: “Enjoy life with a woman whom you love.” Without peace, as it is stated: “You are peace and your house is peace” (I Samuel 25:6). Rabbi Ḥiyya bar Gamda said: He is not even a complete person, as it is stated: “He blessed them and He called their name Adam”³⁰The word adam, which is the name of the first man, simply means “person.” (Genesis 5:2) – when the two of them are not as one they are not called Adam. Some say it diminishes the Divine Image, as it is stated: “Because He created man in the image of God” (Genesis 9:6).
