Spiteful, jealous, and full of love
The God of the Old Testament had a habit of making people sick, often as a form of punishment. My favorite is the story of the poor Philistines who captured the Ark of the Covenant. In 1 Samuel 5:6, we read:
Now the hand of the LORD was heavy on the Ashdodites, and He ravaged them and smote them with tumors, both Ashdod and its territories. (NASB)
The word “tumors” is a nice way of saying hemorrhoids, or, as the KJV translators put it, emerods. In other words, God gave them a wicked case of the piles. Eventually, the populations of Ashdod, Gath, and Ekron wouldn’t sit still for it any longer, and returned the Ark to the Israelites.
More deadly, of course, were the diseases God inflicted upon the Egyptians during the period of bondage. But in the promised land, the Israelites would be safe. In Deuteronomy, he promised to keep his chosen people free of disease.
The LORD will keep you free from every disease. He will not inflict on you the horrible diseases you knew in Egypt, but he will inflict them on all who hate you. (Deut. 7:15, NIV)
So God has complete control over who gets sick and who stays well. What happens if his beloved people stray from the straight and narrow path?
