Easton's Bible Dictionary Lord of Bezek, a Canaanitish king who, having subdued seventy of the chiefs that were around him, made an attack against the armies of Judah and Simeon, but was defeated and brought as a captive to Jerusalem, where his thumbs and great toes were cut off. He confessed that God had requited him for his like cruelty to the seventy kings whom he had subdued (Judges 1:4-7; Comp. 1 Samuel 15:33). Int. Standard Bible Encyclopedia ADONIBEZEK a-do-ni-be'-zek ('adhonibhezeq "lord of Bezek"): Lord of a town, Bezek, in southern Palestine, whom the tribes of Judah and Simeon overthrew. Adonibezek fled when his men were defeated, but was captured, and was punished for his cruelty in cutting off the thumbs and great toes of seventy kings by a similar mutilation. Being brought to Jerusalem, he died there (Judges 1:5-7). This not to be confused with Adonizedek, as in the Septuagint. This is quite another name.
