"There was a woman there who for eighteen years had been possessed by a spirit which drained her of strength. She was badly stooped -- quite incapable of standing erect. When Jesus saw her, he called her to him and said, 'Woman, you are free of your infirmity.' He laid his hand on her, and immediately she stood up straight and began thanking God."
11 And, behold, there was a woman which had a spirit of infirmity eighteen years, and was bowed together, and could in no wise lift up herself.
12 And when Jesus saw her, he called her to him, and said unto her, Woman, thou art loosed from thine infirmity.
13 And he laid his hands on her: and immediately she was made straight, and glorified God.
14 And the ruler of the synagogue answered with indignation, because that Jesus had healed on the Sabbath day, and said unto the people, There are six days in which men ought to work: in them therefore come and be healed, and not on the Sabbath day.
15 The Lord then answered him, and said, Thou hypocrite, doth not each one of you on the Sabbath loose his ox or his ass from the stall, and lead him away to watering?
16 And ought not this woman, being a daughter of Abraham, whom Satan hath bound, lo, these eighteen years, be loosed from this bond on the Sabbath day?
17 And when he had said these things, all his adversaries were ashamed: and all the people rejoiced for all the glorious things that were done by him.
Our Lord Jesus attended upon public worship on the Sabbaths. Even bodily infirmities, unless very grievous, should not keep us from public worship on Sabbath days. This woman came to Christ to be taught, and to get good to her soul, and then he relieved her bodily infirmity. This cure represents the work of Christ's grace upon the soul. And when crooked souls are made straight, they will show it by glorifying God. Christ knew that this ruler had a real enmity to him and to his gospel, and that he did but cloak it with a pretended zeal for the Sabbath day; he really would not have them be healed any day; but if Jesus speaks the word, and puts forth his healing power, sinners are set free. This deliverance is often wrought on the Lord's Day; and whatever labor tends to put men in the way of receiving the blessing, agrees with the design of that day.
