Sixty-seven Jewish men, women and children were slaughtered, and scores wounded, raped and maimed, by their Arab neighbors in the city of Hebron, who rioted for three days amid cries of "Slaughter the Jews." The killings began on Friday afternoon, 17 Av, and most of the victims lost their lives on Shabbat, 18 Av. The survivors were forced to evacuate to Jerusalem, and the ancient Jewish community of Hebron, which had lived in relative peace in the city for hundreds of years, was not revived until after Israel's capture of Hebron in the 1967 Six Day war.

G‑d did not give you light that you may hold it up in the middle of the day.
When you are given light it is in order to accomplish something, to do something difficult and novel.
Go take your light into the dark places and transform them that they may also shine!
