R. Yeshayahu Berlin was a noted Talmudist who served as rabbi in Breslau (today Wroclaw, in Poland). He authored numerous works, but is most famous for his cross references to parallel Talmudic texts mentioned in various tractates. These references, together with those of two previous scholars—R. Yehoshua Boaz and R. Yosef Shmuel—are indispensable for Talmud study, and are printed alongside the text in all standard editions of the Talmud.

The attempted conquest of Acre was a vital part of Napoleon’s Mediterranean campaign against the Ottoman Empire. However, the local troops, supervised by the Pasha’s Jewish advisor Chaim Parchi, valiantly withstood the two-month-long siege. After a final attempt to conquer the city on May 10 (corresponding to 5 Iyar), Napoleon gave up his plans and the siege was lifted.
The British mandate to govern the Holy Land expired on Friday, May 14, 1948. A United Nations resolution passed six months earlier endorsed the establishment of a Jewish state in the biblical homeland of the Jewish people. That afternoon, the state of Israel was proclaimed in Tel Aviv. Four neighboring Arab countries launched a brutal war on Israel's Jewish inhabitants, but were unable to realize their full bloodthirsty intent in circumstances describable only as miraculous. The date--Iyar 5 on the Jewish calendar--is celebrated in Israel as the Israeli "Independence Day."
“The Sages of old instituted, yet in the times of the Holy Temple, that thirty days before the onset of a holiday the teachers should begin publicly instructing the masses regarding the laws of the holiday; e.g. from Purim and onwards to teach the laws of Passover, and from the 5th of Iyar and onwards to teach the laws of Shavuot” (Shulchan Aruch Harav 429:1).
In preparation for the festival of Shavuot, we study one of the six chapters of the Talmud's Ethics of the Fathers ("Avot") on the afternoon of each of the six Shabbatot between Passover and Shavuot; this week we study Chapter Two. (In many communities -- and such is the Chabad custom -- the study cycle is repeated through the summer, until the Shabbat before Rosh Hashanah.)
Tomorrow is the twenty-first day of the Omer Count. Since, on the Jewish calendar, the day begins at nightfall of the previous evening, we count the omer for tomorrow's date tonight, after nightfall: "Today is twenty-one days, which are three weeks, to the Omer." (If you miss the count tonight, you can count the omer all day tomorrow, but without the preceding blessing).
The 49-day "Counting of the Omer" retraces our ancestors' seven-week spiritual journey from the Exodus to Sinai. Each evening we recite a special blessing and count the days and weeks that have passed since the Omer; the 50th day is Shavuot, the festival celebrating the Giving of the Torah at Sinai.
Tonight's Sefirah: Malchut sheb'Tifferet -- "Receptiveness in Harmony"
The teachings of Kabbalah explain that there are seven "Divine Attributes" -- Sefirot -- that G-d assumes through which to relate to our existence: Chessed, Gevurah, Tifferet, Netzach, Hod, Yesod and Malchut ("Love", "Strength", "Beauty", "Victory", "Splendor", "Foundation" and "Sovereignty"). In the human being, created in the "image of G-d," the seven sefirot are mirrored in the seven "emotional attributes" of the human soul: Kindness, Restraint, Harmony, Ambition, Humility, Connection and Receptiveness. Each of the seven attributes contain elements of all seven--i.e., "Kindness in Kindness", "Restraint in Kindness", "Harmony in Kindness", etc.--making for a total of forty-nine traits. The 49-day Omer Count is thus a 49-step process of self-refinement, with each day devoted to the "rectification" and perfection of one the forty-nine "sefirot."
