בַּבֹּ֙קֶר֙ זְרַ֣ע אֶת־זַרְעֶ֔ךָ וְלָעֶ֖רֶב אַל־תַּנַּ֣ח יָדֶ֑ךָ כִּי֩ אֵֽינְךָ֨ יוֹדֵ֜ע אֵ֣י זֶ֤ה יִכְשָׁר֙ הֲזֶ֣ה אוֹ־זֶ֔ה וְאִם־שְׁנֵיהֶ֥ם כְּאֶחָ֖ד טוֹבִֽים׃
너는 아침에 씨를 뿌리고 저녁에도 손을 거두지 말라 이것이 잘 될는지, 저것이 잘 될는지, 혹 둘이 다 잘 될는지 알지 못함이니라
Pirkei Avot
Moses received the Torah at Sinai and transmitted it to Joshua, Joshua to the elders, and the elders to the prophets, and the prophets to the Men of the Great Assembly. They said three things: Be patient in [the administration of] justice, raise many disciples and make a fence round the Torah.
Mishnah Ketubot
A virgin is married on the fourth day [of the week] and a widow on the fifth day, for twice in the week the courts sit in the towns, on the second day [of the week] and on the fifth day, so that if he [the husband] had a claim as to the virginity [of the bride] he could go early [on the morning of the fifth day of the week] to the court.
