How different are the Philistines and Israelite's?
god punishes the isrealites by letting them fall victim to the philistines and killing important men.
"[The LORD] struck at the men of Beth-shemesh because they looked into the Ark of the LORD; He struck down seventy men among the people [and] fifty thousand men. The people mourned, for He had inflicted a great slaughter upon the population." 1 Samuel 6:19
"The hand of the LORD lay heavy upon the Ashdodites, and He wrought havoc among them: He struck Ashdod and its territory with hemorrhoids." 1 Samuel 5:6
God punishes the philistines with hemorrhoids and vandalism
If anything, gods punishment on the Israelite's is MORE harsh then the punishments for the Philistines.
That's not fair!
The point of being chosen isn't to make you superior to everyone else, its to hold you to a higher standard
just because someone is favored or held to a higher standard doesn't make them immune to mistakes.
