Bezek

Hebrew: בֶּזֶק —transliteration: Bezeq —meaning: lightning or flash

This is the name of two biblical places.

Bezek, mentioned in 1 Samuel

This military staging ground is the place where King Saul numbered the forces of Israel and Judah (1 Samuel 11:8). It was somewhere in the center of the country.

Eusebius, Onomasticon speaks of two villages of this name 17 Roman miles from Shechem, on the way to Scythopolis. No doubt Khirbet Ibziq is intended. Here, or on the neighboring height, Ras Ibziq, a mountain 2,404 ft. above sea level, the army probably assembled. —International Standard Bible Encyclopedia

It is probably the modern village Ibziq, Israel (aka Ibzik, aka Khirbet Ibzik), 13 miles northeast of Shechem. Iziq contains 2 ruins separated by one kilometer and referred to in the Manasseh Hill Country Survey as Khirbet Ibziq (Lower, al-Tahta) and Khirbet Ibziq (Upper, al-Fauqa), aka Khirbet Ibzik and Tel Ibziq. The upper site is known to contain a variety of pottery fragments extending from the Iron Age and races of ruins, cisterns and caves. These sites are about 12 miles (20 kilometers) northeast of Nablus, Israel.

Bezek, the residence of King Adoni-Bezek

This was located somewhere in the tribe of Judah’s allotment (Judges 1:4-5).

It is possibly related to the area later once called Bezkah or Bezqah in Israel.
