אֵיכָה֩ יָעִ֨יב בְּאַפּ֤וֹ ׀ אֲדֹנָי֙ אֶת־בַּת־צִיּ֔וֹן הִשְׁלִ֤יךְ מִשָּׁמַ֙יִם֙ אֶ֔רֶץ תִּפְאֶ֖רֶת יִשְׂרָאֵ֑ל וְלֹא־זָכַ֥ר הֲדֹם־רַגְלָ֖יו בְּי֥וֹם אַפּֽוֹ׃ (ס)
슬프다 주께서 어찌 그리 진노하사 처녀 시온을 구름으로 덮으셨는고 이스라엘의 아름다운 것을 하늘에서 땅에 던지셨음이여 진노하신 날에 그 발등상을 기억지 아니하셨도다
Mishneh Torah, Fasts
Torah scholars should not greet each other on the Ninth of Av. Rather they sit sadly and sigh like mourners. And if an ignorant person greeted them, they may return his greeting with a soft voice and a serious demeanor. And it is forbidden on the Ninth of Av to read the Torah, the Prophets, the Writings, the Mishnah, the laws, the Gemara and the aggadah. One may only read from Job, Lamentations and from bad things in Jeremiah. And we make the infants of the house of their teacher idle (we do not have them study). And some sages are accustomed to not laying the head tefillin.
