Adoni-Bezek, also written Adonibezek or Adoni Bezek, was a Canaanite king referred to in the Hebrew Bible in Judges 1:4–7. Previous to the occupation of Canaan by the Israelites, he had subdued seventy of the kings of cities around him. The tribes of Judah and Simeon attacked the Canaanites and the Perizzites at Bezek and defeated him.
The historical reality of events described in the book of Judges is the subject of ongoing dispute among scholars, who vary in their opinions about how much of the book is historical.
