Read Luke 8:29 Using Other Translations
(For he had commanded the unclean spirit to come out of the man. For oftentimes it had caught him: and he was kept bound with chains and in fetters; and he brake the bands, and was driven of the devil into the wilderness.)
For he had commanded the unclean spirit to come out of the man. (For many a time it had seized him. He was kept under guard and bound with chains and shackles, but he would break the bonds and be driven by the demon into the desert.)
For Jesus had already commanded the evil spirit to come out of him. This spirit had often taken control of the man. Even when he was placed under guard and put in chains and shackles, he simply broke them and rushed out into the wilderness, completely under the demon’s power.
