Bible Verses About Sickness: Often sent as a punishment of sin

"'But if you will not listen to me and obey all these mitzvot,

if you loathe my regulations and reject my rulings, in order not to obey all my mitzvot but cancel my covenant;

then I, for my part, will do this to you: I will bring terror upon you -wasting disease and chronic fever to dim your sight and sap your strength. You will sow your seed for nothing, because your enemies will eat the crops.

A letter came to him from Eliyahu the prophet which said, "Here is what ADONAI, the God of David your ancestor, says: 'You have not lived by the examples of Y'hoshafat your father or Asa king of Y'hudah.

Instead you have lived by the example of the kings of Isra'el and have caused Y'hudah and the people living in Yerushalayim to prostitute themselves, just as the house of Ach'av caused [Isra'el] to prostitute themselves. Moreover, you killed your brothers from your father's house, men better than you.

Because of all this, ADONAI is going to strike your people with a terrible disease, also your children, your wives and everything you have.

You will be very ill from a disease in your intestines, until your intestines protrude, because of the effects of this disease, day after day.'"

This is why many among you are weak and sick, and some have died!
