What did the Israelites to do king Adonibezek when they captured him?

They cut off his thumbs and big toes.

And they found Adonibezek in Bezek: and they fought against him, and they slew the Canaanites and the Perizzites.

But Adonibezek fled; and they pursued after him, and caught him, and cut off his thumbs and his great toes. Judges 1:5-6
