John Gill Commentary Judges 1:5

"And they found Adoni-bezek in Bezek; and they fought against him, and they smote the Canaanites and the Perizzites." — Judges 1:5 (ASV)

And they found Adonibezek in Bezek
Who was king of, the place, and whose name signifies lord of Bezek; not that they took him there, for he is afterwards said to make his escape from thence, but here he was when they came against that city, and into which they rushed upon him, and fell upon him as follows:

and they fought against him ;
entering the city with their forces:

and they slew the Canaanites and the Perizzites :
that were in it, or about it, even to the number of ten thousand, as before related, (Judges 1:4) .
