The Philistine lords, including early Philistine kings like Abimelech held close bloodline ties to the southern Hyksos Aamu and the Greater/northern Hyksos Shemau and their spawned the Indo-Aryan settlements of Caphtor, Caphtorim, and Kefitiu, with the latter being the Caphtorim transliteration in the Egyptian New Kingdom Records. Understanding this is the key to revealing the identity of the enigmatic “lords of the Philistines,” and how some of their pentapolis city-states became controlled by Avvim and Anakim within the Philistine confederacy.
Anakim in the time of the Covenant Land conquest controlled Gath and Ashod, and perhaps other parts of Gaza, while the Avvim controlled Gaza/Azzah city as the Gazathites/ha`Azzathiy. Hence, the Philistines replaced much Avvim and Anakim, but Philistines permitted Anakim and Avvim to control three of the five pentapolis city-states, and to dwell among Philistines, Caphtorim, Cherethim, and Pelethim, as opposed to driving the Anakim and Avvim completely out. Philistines were centered at Eshkalon and Ekron. The Avvim dwelled from Sihor to Egypt (Josh 13:3), and from Hazerim to Azzah (Deut 2:23) before they were absorbed into the “Canaanite five lords of the Philistines” hegemony.
The Philistine confederacy was a military superpower of warrior giants and hybrid humans before and after the Covenant Land conquest, a networked nation of city-state fortresses designed for perpetual war. The Avvim’s Hazerim/Chatseriym walled towns and villages were incorporated into the Hyksos inspired city-state military complex. Hazerim’s singular format, Chatsowr from Chatser, means towns and cities protected by walls. The Philistine innovation spread to the Eastern and Northern alliances of giants. King Jabin’s pentapolis that Joshua battled in the northern campaign included his royal city of Hazor/Chatsowr that derives from Chatser. The twelve pentapolis city-state fortresses of King Og’s empire included unwalled villages as part of their defensive military strategies, the praziy of the Perizzim.
