I read 1 Samuel 5 which tells about the ark of God which was captured by the Philistines. They placed it in the temple of their God, Dagon. But their God (or the idol that represented it) fell down repeatedly and broke. God’s hand was heavy on any town that the ark was in, inflicting its residents with tumors and inciting fear into all of the Philistine people. They decided it probably should go back to the territory of the Israelites.
