EKRON

  Ekron is the one of the five town that was owned by the Philistine lord which is the farthest town north and was the farthest from the sea.  Located in the lowlands were several Philistine cities.  The five Philistine rules of these cities were the Gazites, the Asdodites, the Ashkelonites, the Gitties, the Ekronites and the Avvites. (Joshua 13:3).
The five towns were assigned to Judah, then Dan but went back to the Philistines. Ekron was the last place the ark was carried before sent back to Israel. In Ekron  was a noted sanctuary of Baalzebub found in (2ki 1:2, 2Ki 1:3, 2Ki 1:6,16 ). 
 Reading in 2 Kings 1:16  Elijah spoke to the king Ahaziah  that the Lord told him,because he consulted with Beelzebub (Baalzebub: Literally, "the lord of flies;" or, as the LXX render, Βααλ μυεαν θεον, Baal the fly god. See note on Exo_8:24.)
In  1 Sam 17:52 it shows that Israel and Judah got up with a shout and pursued the Philistines as far as the entrance to the valley and to the gates of Ekron.

From the Assyrian records we learn that Assyria revolted against Sennacherib and expelled Padi, the governor that had been placed over it, and sent him to Hezekiah, at Jerusalem, for safe keeping. Sennacherib marched against it and Ekron called in the aid of the king of Mutsri, formerly  Egypt but now regarded by some scholars as a district of Northwestern Arabia. Sennacherib raised the siege of Ekron to defeat this army, which he did at Eltekeh, and then returned and took the city by storm and put to death the leaders of the revolt and carried their adherents into captivity. He then compelled Hezekiah to restore Padi, who was once more made governor. This  led to the famous attack of Sennacherib on Hezekiah and Jerusalem (Rawl., Anc. Mon., II, 159). Ekron is mentioned in 1 Macc 10:89 as being given by Alexander Balas to Jonathan Maccabeus, and it appears in the accounts of the first Crusade.
