“And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross” (Colossians 2:15)
There is an account in the book of Judges where the tribe of Judah was sent to fight against the Canaanites (Judges 1). As they set out, God delivered the Canaanites and Perizzites into the Israelites hands. When they captured the Canaanite king solidifying their victory, they cut off his big toes and thumbs then paraded him as a conquered foe.
While this practice seems foreign, it was very effective. First because the king had no big toe, he would never be able to stand and fight again. Secondly, because he had no thumbs, he would never be able to hold a sword in battle again. Lastly, because he was on display as a defeated king striped of power and dignity, if he ever tried to assemble an army he would be discounted immediately. He has been overthrown, defeated, publically shamed, humiliated, conquered and crushed.
Not only would he never be able to raise an army again, everyone who saw him would know what had happened. In the same way...
