'Threshold' in the Bible

But when they arose early the next morning, behold, Dagon had fallen on his face to the ground before the ark of the Lord. And the head of Dagon and both the palms of his hands were cut off on the threshold; only the trunk of Dagon was left to him.

Therefore neither the priests of Dagon nor all who enter Dagon’s house tread on the threshold of Dagon in Ashdod to this day.
