'Threshold' in the Bible

When they got up early in the morning the next day, {there was} Dagon fallen [again] with his face to the ground before the ark of Yahweh! The head of Dagon and the palms of his two hands were cut off, lying at the threshold; only [the body] of Dagon was left.

(Therefore the priests of Dagon and all who come into the house of Dagon do not tread on the threshold of Dagon in Ashdod until this [very] day.)
