John Lightfoot on Luke 13:11

[Having a spirit of infirmity.] I. The Jews distinguish between spirits, and devils, and good angels. "All things do subserve to the glory of the King of kings, the holy blessed One, even spirits, also devils also ministering angels."

The difficulty is in what sense they take spirits, as they are distinguished from angels and devils: when it is probable they did not mean human souls. But these things are not the business of this place.

II. Therefore, as to this phrase in St. Luke, a spirit of infirmity, let us begin our inquiry from this passage: "It is written, 'If I put the plague of leprosy in a house of the land of your inheritance.' R. Judah saith, 'This foretells such plagues to come upon them.' R. Simeon saith, 'He excepts those violent plagues that do not render a man unclean.'" Where the Gloss is, If those plagues come by the insufflation of the devil, which do not defile the man. And the Gemara a little after; "Rabba saith, He excepts the plagues of spirits. Rabh Papa saith, 'He excepts the plagues of enchantments.'" Where the Gloss again hath it; "Those plagues which are inflicted by the insufflation of the devil, not by the hands of men."

I. You see, therefore, first, that it was a most received opinion amongst the Jews, that diseases or plagues might be inflicted by the devil. Which is plain also from the evangelists; because our Saviour, in this very place, tells us, that the bowing together of this woman was inflicted upon her by Satan.

II. They conceived further, that some diseases were inflicted that were unclean, and some that were not unclean. The unclean were the leprosy, issues, &c.; not unclean, were such as this woman's infirmity, &c.

III. They distinguish betwixt an evil spirit, and an unclean spirit. Not but they accounted an unclean spirit ill enough, and an evil spirit to be unclean enough; but that they might distinguish the various operations of the devil, as also concerning the various persons possessed and afflicted by him.

1. They acknowledged that evil spirits might inflict diseases. "Whomsoever either the Gentiles, or evil spirit drive," i.e. beyond the bounds of the sabbath. Where the Gloss is; "The evil spirit is the devil that hath entered into him, disturbs his intellectuals, so that he is carried beyond the bounds." But Rambam saith, "They call all kind of melancholy an evil spirit." And elsewhere: an evil spirit, i.e. a disease.

2. The unclean spirit amongst them was chiefly and more peculiarly that devil that haunted places of burial, and such-like, that were most unclean. The unclean spirit, i.e. the devil that haunts burying-places. "Thither the necromancer betook himself" (as the Gemara hath it, which I have also quoted in another place); "and when he had macerated himself with fasting, he lodgeth amongst the tombs, to the end that he might be the more inspired by the unclean spirit." Nor is it much otherwise (as they themselves relate it) with the python or prophesying spirit. "For the Rabbins deliver: the python is he that speaks within the parts." The Gloss is, "He that raiseth a dead person, and sits between the parts of the bones," &c.

Hence that reason of our conjecture concerning that demoniac, Luke 4:33; that he was either a necromancer or pythonist, taken from that unusual way of expressing it which is there observable, not having an unclean spirit, nor having an unclean devil, but having a spirit of an unclean devil.

There were therefore two sorts of men whom they accounted under the possession of an unclean spirit, in their proper sense so called: those especially who sought and were ambitious to be inspired of the devil amongst tombs and unclean places; and those also, who, being involuntarily possessed by the devils, betook themselves amongst tombs and such places of uncleanness. And whether they upon whom the devil inflicted unclean diseases should be ranked in the same degree, I do not determine. There were others who were not acted by such diabolical furies, but afflicted with other kind of diseases, whom they accounted under the operation of an evil spirit of disease or infirmity. Not of uncleanness; but of infirmity. And perhaps the evangelist speaks according to this antithesis, that this woman had neither a spirit of uncleanness, according to what they judged of a spirit of uncleanness; nor a disease of uncleanness; but a spirit of infirmity.
