Jesus went all over Galilee teaching in the [Jewish] synagogues and preaching the good news of the [coming, see verse 17] kingdom, and healing all kinds of disease and sickness among the people.
When evening came they brought many persons who were dominated by evil spirits to Jesus and He drove out the spirits with [just] a word and healed all those who were sick.
And just then [He met] a woman who had an [evil] spirit that had caused her to be deformed for eighteen years. She was bent over and could not raise herself up. [Note: This was probably osteomyelitis or osteoporosis].
So, should not this woman, being a daughter [i.e., descendant] of Abraham, whom Satan has bound [with this disease] for eighteen years, have been released from this bondage on the Sabbath day?”
