'Threshold' in the Bible

And they rise early in the morning on the morrow, and lo, Dagon is fallen on its face to the earth, before the ark of Jehovah, and the head of Dagon, and the two palms of its hands are cut off at the threshold, only the fishy part hath been left to him;

therefore the priests of Dagon, and all those coming into the house of Dagon, tread not on the threshold of Dagon, in Ashdod, till this day.
