1 Sam 5:7
Send away the ark of the God of Israel, and let go again to his own place, that it slay us not, and our people
The Philistines had captured the Ark of the Covenant from the Israelites here in 1 Samuel during the battle of Aphek. Little did they realize what was about to happen to them. God brought devastation and “tumors” to their city, much like He did with the Egyptians.
