Deuteronomy 28:35

35.The Lord shall smite thee in the knees. Since death is common to the whole human race, they must needs also be all subject to disease; nor is it a matter of surprise that the whole posterity of Adam, which is infected with the taint of sin, should so be liable to many afflictions, which are the wages of sin. But, since the offenses of all are not alike, God also maintains a just proportion in the execution of His various punishments; thus, in this passage He does not speak only of common maladies, but of those whereby He openly shews His vengeance against the transgressors of the Law; of which sort are incurable diseases.
