Horvat Diab
Ḥorvat Diab or Horbat Diab is an archaeological site located in the central West Bank, near Biddu, Giv'on HaHadasha, and Beit Ijza. Excavations uncovered the remains of a substantial Jewish estate farm that was occupied from the late 2nd century BCE until the [First Jewish–Roman War|First Jewish Revolt] against Rome, after which it was abandoned.
The complex included a hall with stone benches and a nearby mikveh. Based on its layout and parallels from other synagogues of the late Second Temple period, the excavator, Benjamin Har-Even, identified the structure as a simple synagogue serving the estate's inhabitants. If this interpretation is correct, it would place the site among the synagogues in Palestine|earliest known synagogues] in the southern Levant. A cemetery from the Second Temple period, featuring rock-cut tombs typical of that era, lies on the northern and eastern slopes.
Geography
The site is situated atop a hill at an elevation of c. 750 m above sea level, on a plateau overlooking Wadi Salman. The ancient road between Jaffa and Jerusalem, which climbed the Bethoron ascent, passed nearby. In modern times, the site lies in the West Bank, not far from Jerusalem, in the vicinity of Biddu, Giv'on HaHadasha, and Beit Ijza.Archaeology
The site appears to have been a large estate farm belonging to an extended Jewish family in the late Second Temple period. Numismatic evidence indicates that the settlement was inhabited from the late 2nd century BCE until the First Jewish Revolt against Rome, after which it was abandoned.Synagogue
Excavations exposed a residential complex covering about 4 dunams. One room is a transverse hall, measuring 7.5 × 3.5 m, detached from the other rooms of the wing and constitutes a separate unit. Benches of dressed ashlar were installed on either side of its entrance and along parts of the walls; the stones preserve chisel marks characteristic of Second Temple–period masonry. A mikveh was excavated nearby.Based on the hall’s architectural layout, its benches, the presence of a nearby mikveh, and its resemblance to early synagogues discovered at Masada, Herodium, Gamla, Kiryat Sefer, Modi'in, and Magdala, the site's excavator Benjamin Har-Even suggested that this hall functioned as a synagogue, serving the inhabitants of the estate. This identification has been adopted by several scholars, including Rina Talgam, Dina Avshalom-Gorni, and Arfan Najar. Not all agree, however: Ze'ev Weiss questions the synagogue interpretation, arguing that the small, bench-lined hall is better understood as a family or guest-reception space rather than a prayer hall.
Cemetery
The cemetery serving the settlement lies on the northern and eastern slopes. It includes rock-hewn tombs characteristic of the Second Temple period.Finds
Numerous tools were found on site, some made of basalt, along with characteristic stone vessels and a few coins dating from the Hasmonean and Herodian kingdoms, and the first century CE, the latest from the second year of the First Jewish Revolt.Research History
The first archaeological survey at the site took place in 1968 as part of the Emergency Survey, when the site was identified as a Roman-period cemetery. A subsequent survey within the "Land of Benjamin Survey" documented remains of an ancient ruin as well.In 2005, a salvage excavation was carried out by Benjamin Har-Even on behalf of the Staff Officer for Archaeology in the Civil Administration of Judea and Samaria, in conjunction with construction of the West Bank barrier. The work, focused on the site's western slopes, exposed architectural remains, including a residential complex and a public building.
