Ekron

Joshua 13:3

from the Shihor [waterway] which is east of Egypt [at the southern end of Canaan], northward to the border of Ekron (all of it regarded as Canaanite); the five rulers of the Philistines: the Gazite, Ashdodite, the Ashkelonite, the Gittite, the Ekronite; and the Avvite

1 Samuel 5:10

So they sent the ark of God to Ekron. And as the ark of God came to Ekron, the Ekronites cried out, “They have brought the ark of the God of Israel [from Gath] to us, to kill us and our people.”

1 Samuel 6:17

These are the golden tumors which the Philistines returned as a guilt offering to the Lord: one for Ashdod, one for Gaza, one for Ashkelon, one for Gath and one for Ekron [the five chief cities of the Philistines];

Amos 1:8

“And I will cut off and destroy the inhabitants from Ashdod,
And the ruler who holds the scepter, from Ashkelon;
And I will unleash My power and turn My hand [in judgment] against Ekron,
And the rest of the Philistines [in Gath and the towns dependent on these four Philistine cities] shall die,”
Says the Lord God.

Zephaniah 2:4

For [this is the fate of the Philistines:] Gaza will be abandoned
And Ashkelon a desolation;
[The people of] Ashdod will be driven out at noon [in broad daylight]
And Ekron will be uprooted and destroyed.

Zechariah 9:5-7

Ashkelon will see it and fear;
Gaza will writhe in pain,
And Ekron, for her hope and expectation, has been ruined.
The king will perish from Gaza,
And Ashkelon will not be inhabited.
