Charles Ellicott Commentary Luke 13:16

"And ought not this woman, being a daughter of Abraham, whom Satan had bound, lo, [these] eighteen years, to have been loosed from this bond on the day of the sabbath?" — Luke 13:16 (ASV)

Whom Satan hath bound.—The words imply the belief that there was another source than mere bodily disease for the infirmity—in part, at least, the belief that all disease—or very many forms of it—is directly or indirectly traceable to the power of the Enemy. So St. Paul’s thorn in the flesh—assuming it to be some sharp bodily suffering—is the messenger of Satan. (See Note on 2 Corinthians 12:7.)

It is obvious that this narrative would have for one like St. Luke a special interest over and above that which like narratives had for the other Evangelists. We can scarcely fail to think of the beloved physician as practising his art for the good of men, his brothers, on the Sabbath, as on other days. In doing so he would doubtless be met, on the part of Jews and Judaisers, with words like those of the ruler of the synagogue, There are six days on which men ought to work; do thy work of healing on them. For such a one it would be a comfort unspeakable to be able to point to our Lord’s words and acts as sanctioning his own practice.
