Tomorrow is the tenth day of the Hebrew month of Tevet, a fast day that commemorates the beginning of the Babylonian siege of Jerusalem in 587 BCE. Originally, the two preceding days were also days of fasting. While the reasons for the fast of 9 Tevet are shrouded in mystery, the fast of 8 Tevet (in Yiddish, khes Teyves) mourns the composition of the Septuagint, the Greek translation of the Hebrew Bible produced in the 3rd or 2nd century BCE—according to legend, by a group of 70 Jewish elders. In the ancient world, the Septuagint made the Tanakh accessible to Greek-speaking Jews, such as the Alexandrian philosopher Philo, as well as to Gentiles—early Christians among them.

The fast of 8 Tevet was a subject of particular fascination to Rabbi Moses Schreiber (a/k/a the Chasam Sofer), a sage of tremendous erudition and an early pioneer of Orthodoxy, who spent much effort combating the early phases of Reform Judaism and the inroads of modernity. Elli Fischer—a translator of Hebrew books by profession—discusses the history of this day, and why it held such attraction to Schreiber. (Audio, 46 minutes.)

Yesterday, the beepers used by hundreds of Hizballah operatives were detonated. Noah Rothman puts this ingenious attack in the context of the overall war between Israel and the Iran-backed terrorist group:

[W]hile the disabling of an untold number of Hizballah operatives is remarkable, it’s also ominous. This week, the Israeli defense minister Yoav Gallant told reporters that the hour is nearing when Israeli forces will have to confront Iran’s cat’s-paw in southern Lebanon directly, in order to return the tens of thousands of Israelis who fled their homes along Lebanon’s border under fire and have not yet been able to return. Today’s operation may be a prelude to the next phase of Israel’s defensive war, a dangerous one in which the IDF will face off against an enemy with tens of thousands of fighters and over 150,000 rockets and missiles trained on Israeli cities.

Seth Frantzman, meanwhile, focuses on the specific damage the pager bombings have likely done to Hizballah:

This will put the men in hospital for a period of time. Some of them can go back to serving Hizballah, but they will not have access to one of their hands. These will most likely be their dominant hand, meaning the hand they’d also use to hold the trigger of a rifle or push the button to launch a missile.

Hizballah has already lost around 450 fighters in its eleven-month confrontation with Israel. This is a significant loss for the group. While Hizballah can replace losses, it doesn’t have an endlessly deep [supply of recruits]. This is not only because it has to invest in training and security ahead of recruitment, but also because it draws its recruits from a narrow spectrum of Lebanese society.

The overall challenge for Hizballah is not just replacing wounded and dead fighters. The group will be challenged to . . . roll out some other way to communicate with its men. The use of pagers may seem archaic, but Hizballah apparently chose to use this system because it assumed the network could not be penetrated. . . . It will also now be concerned about the penetration of its operational security. When groups like Hizballah are in chaos, they are more vulnerable to making mistakes.
