'Severe' in the Bible

In the thirty-ninth year of his reign, Asa developed a disease in his feet, and his disease became increasingly severe. Yet even in his disease he didn’t seek the Lord but only the physicians.

This continued day after day until two full years passed. Then his intestines came out because of his disease, and he died from severe illnesses. But his people did not hold a fire in his honor like the fire in honor of his fathers.
