Concise Bible Dictionary:
The kingdom of Satan was spoiled by One stronger than he when the Lord Jesus cast out demons from those possessed, and also especially when Satan’s power was annulled on the cross (Matt. 12:29; Mark 3:27; Col. 2:15; Heb. 2:14). The Hebrew believers had taken joyfully the plunder of their goods (Heb. 10:34). The Colossians were warned lest any should spoil (make a prey of) them through philosophy (Col. 2:8), a caution surely needed in the present day.
