Judges 1:6 - Coke's Commentary on the Holy Bible

And Adoni-bezek fled— It is evident, that after the battle the king shut himself up in Bezek; that then this place was besieged; that the two confederated tribes took it; but that Adoni-bezek having escaped thence, they sent detachments after him, who overtook and brought him back to the camp of the conquerors; and they cut off his thumbs, and his great toes. This was but a just requital, as he himself acknowleged, of the barbarity that he had committed upon so many other princes. By treating Adoni-bezek thus, they disabled him from handling arms, or supporting himself in flight, two things essential in a warrior. This is not an unknown punishment in prophane history; for Elian, in his Hist. Var. lib. ii. c. 9. relates, that the Athenians cut off the thumbs of the inhabitants of the island of Egina, that those islanders might not dispute with them the empire of the sea.
