you repent, you will all likewise perish. Or those eighteen on whom the tower in Siloam fell and killed them: do you think that they were worse offenders than all the others who lived in Jerusalem? No, I tell you; but unless you repent, you will all likewise perish.” His mention of the fall of the Tower of Siloam added a nuance to his prior point: accidents happen. Therefore, even in the absence of persecution, death can come unexpectedly to anyone, irrespective of how righteous or how sinful they are. He may have been emphasizing that the time granted by God for repentance is limited.

According to Luke's account, Jesus was teaching in a synagogue on the Sabbath day, when he observed a woman who had been crippled "by a spirit" for eighteen years, and healed her with the words "You have been set
