'Threshold' in the Bible

But when they got up the next morning, there was Dagon, lying on the ground again in front of the Ark of the LORD. Dagon's head and both of his arms were broken off and lying on the threshold. Only the trunk of Dagon was left intact.

This is why neither the priests of Dagon nor anyone who enters the temple of Dagon step on the threshold of Dagon in Ashdod to this day.
