Micah 6:12-13:

For the rich men thereof are full of violence, and the inhabitants thereof have spoken lies, and their tongue is deceitful in their mouth.
Therefore also will I make thee sick in smiting thee, in making thee desolate because of thy sins.

Notes on Micah 6:12-13:

This is another passage showing the link between sin and sickness.  Jesus took care of your sin problem, so you have the right to be free from sickness, which is a judgment on sin.
