We see that even then that a tragedy of the State of Israel is hinted to in this prophecy.
◾And we will bring down an essay about the helicopter tragedy from Dr. Moshe Katz that deals with skips in the Torah. In it, we see a great connection between the tragedy and the number 73, which is the number of the current year: 5773: On Tuesday, the 28th of Shevat, 5757, a terrible tragedy occurred that is known as "The helicopter tragedy". The tragedy occurred when 2 Yas'ur helicopters belonging to the IDF crashed into each other in the skies of Northern Israel at the time that they were carrying soldiers from the Nahal (Yesod) Brigade to Southern Lebanon. The accident occurred over the Yishuv that is called "She'ar Yashuv". In the incident, 73 people on the helicopters were killed. The incident occurred between Parshat Yitro and Parshat Mishpatim. In the Haftara of Parshat Yitro appear the following verses: "Then said the LORD unto Isaiah: 'Go forth now to meet Ahaz, thou, and Shear-jashub thy son, at the end of the conduit of the upper pool, in the highway of the fullers' field; and say unto him: Keep calm, and be quiet; fear not, neither let thy heart be faint, because of these two tails of smoking firebrands, for the fierce anger of Rezin and Aram, and of the son of Remaliah." The connection between the verses and the tragedy is bone-chilling, and was publicized on all forms of media. An entire country is enwrapped in heavy sorrow. Let's delve into the details:
◾the Haftara of the Parshat Hashavu'a when the tragedy occurred, it was Chapter 7 and verse 3. This hints to the 73 fatalities who fell in the tragedy.
◾"She'ar Yashuv" was mentioned in the verses and "two tails of smoking firebrands" and "fierce anger".
◾In She'ar Yashuv at the time of the tragedy, 73 families lived in the Yishuv.
◾In Parshat Mishpatim, read on the Shabbat after the tragedy, this verse appears: "Then went up Moses, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel", meaning Moshe went up with 73 other important people in Israel. Again, the number 73.
◾Rav Shlomo Reiskin adds that the tragedy occurred in the Galil גליל, which has the gematria of 73.
◾Also, in the year 1973 was a great crisis for the State of Israel, the Yom Kippur War, when their Kohi Ve'otzem Yadi fell.
◾Also, Route 73 in the Galil starts at Adashim Interchange - צמת עדשים - which has the gematria of משיח בן דוד. And it ends at Nehalel Interchange - צמת נהלל - hinting to the Great Hallel with which we will praise Hashem in the Geula. And the road crosses the Yishuv called Ramat David. Rav Avraham Weinberg adds that David and Shelomo together ruled [in Yerushalayim] for 73 years.
◾Also, when searching in Torah codes for the minimal meeting between "אסון" and "המסוקים", a table shows the minimal meeting, and shows כ"ח שבט, along with שאר and ישוב.
