Not any one who enter Dagon’s temple at Ashdod step on the threshold

1 Samuel 5:1-12
That is why to this day neither the priests of Dagon nor any others who enter Dagon’s temple at Ashdod step on the threshold.
The Lord’s hand was heavy on the people of Ashdod and its vicinity; he brought devastation on them and afflicted them with tumors.
But after they had moved it, the Lord’s hand was against that city, throwing it into a great panic. He afflicted the people of the city, both young and old, with an outbreak of tumors.
So they called together all the rulers of the Philistines and said, “Send the ark of the god of Israel away; let it go back to its own place, or it will kill us and our people.” For death had filled the city with panic; God’s hand was very heavy on it.
Why?
The Ark of Covenant has God's Spirit, Israelite brought it to the war but God did not help Isreal. Now it is in the Philistine's area, God pulled down the Dagon's hands and head, make great panic to them, and bring them with an outbreak of tumors
So the Ark of Covenant stayed in Philistine is a disaster to them, so all of them hope it could be moved away from them.
The Lord is holy, could not be mistreated, God is beyond any gods in the world.
The same custom is existing in Taiwan either that does not step on the threshold when entering Temples.
How?
Give honor to the Lord and give thanks to the Lord, praise the Lord forever
