Midrash su Giobbe 5:24

A man must say three things in his house on Friday when it is becoming dark: "Have you set aside the tithes?" "Have you put up the Erub?" and "Light the [Sabbath] candles." Whence do we learn this? R. Joshua b. Levi said: "The passage says (Job 5, 24.) And thou shalt know that there is peace in thy tent, and thou wilt look over thy habitation, and shalt miss nothing."

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.
