The Holy Bible says that king Asa had a disease of the feet. It could have been diabetes, we don't know; but whatever it was, it had become exceedingly worse. Most people develop feet problems in old age. Asa had a serious condition in his feet, which was deadly. The Old Testament tells us that king Asa sought help from the physicians, but He didn't seek healing from The Great Physician (the Lord Jesus Christ). Asa called for the doctors, placing his sole trust in man to heal him, but Asa foolishly failed to pray to the Lord for healing, and he died. All Asa had to do was pray, and he would have been healed and would have continued to live.
