The strong man teaches that Jesus' victory over demons displays a stronger power binding the enemy.

²⁹Or else how can one enter into a strong man’s house, and spoil his goods, except he first bind the strong man? and then he will spoil his house.

²⁷No man can enter into a strong man’s house, and spoil his goods, except he will first bind the strong man; and then he will spoil his house.

²¹When a strong man armed keepeth his palace, his goods are in peace:

²²But when a stronger than he shall come upon him, and overcome him, he taketh from him all his armour wherein he trusted, and divideth his spoils.
