'Doorstep' in the Bible

And when they got up early on the morning after, Dagon had come down to the earth on his face before the ark of the Lord; and his head and his hands were broken off on the doorstep; only the base was in its place.

So to this day no priest of Dagon, or any who come into Dagon's house, will put his foot on the doorstep of the house of Dagon in Ashdod.
