In 2 Kings xxv. 8, the seventh of Ab is the date given for the
first of these events, whereas Jeremiah (lii. 12) mentions the
tenth as the fatal day. Josephus (Wars of the Jews, Book vi.
chap. 4, sec. 15) coincides with the latter.
On the ninth of Ab one must abstain from eating and drinking, and
anointing one's self, and wearing shoes, and matrimonial intercourse. He
may not read the Bible, the Talmud, the Midrash, the Halachoth, or the
Haggadoth, excepting such portions as he is not in the habit of reading,
such he may then read. The lamentations, Job, and the hard words of
Jeremiah should engage his study. Children should not go to school on
this day, because it is said (Ps. xix. 8), "The statutes of the Lord are
right, rejoicing the heart."
