Albert Barnes Commentary Judges 12:8

"And after him Ibzan of Beth-lehem judged Israel." — Judges 12:8 (ASV)

Ibzan of Bethlehem - Some have supposed him the same as Boaz (Ruth 2:1) of Bethlehem-Judah. Others, from the juxtaposition of Elon the Zebulonite (Judges 12:11), understand Bethlehem in the tribe of Zebulon (Joshua 19:15).
