ISB ~ John 9 v2

Rabbi, who sinned … ?:Sickness was thought to be a direct consequence of sin (Job 31:3; Ps 107:17). Responsibility for physical ailments was imputed either to one’s parents (Tob 3:3) or to the earliest period of one’s life, since certain rabbis taught that infants could sin before birth (9:34). Jesus does not deny the principle that sickness is brought on by sin, but that a personal link can be established in every case.
