1 Samuel 11:8 (ESV)

8 When he mustered them at Bezek, the people of Israel were three hundred thousand, and the men of Judah thirty thousand.

Bezek was high up in the mountains, about fifteen kilometres to the west of the Jordan River and opposite the town of Jabesh-gilead.1 Previously, in Judges 1:4–5, it was the rallying point for a war against the Canaanites and now it serves as the rallying point for the united attack against the Ammonites.2
