Most everyone has heard of the 8th/9th century BC Kuntillet ‘Ajrud inscriptions that mention Yahweh and his Ashera, that is that Yahweh was understood as having a female consort. Interesting as that is, often overlooked in the inscriptions are the names of the god Yahweh himself. The writings are themselves apparently practice work by scribes learning the trade and cover many topics. But of interest now are the blessings given in the name of "Yahweh of Samaria" and "Yahweh of Teman", or simply 'Yahweh Samaria' and 'Yahweh Teman'. What this suggests is that Yahweh was regarded as a regionalized deity much like Baal who was often referred to by regional names like Baal of Gad, Ba‘al Hermon, Ba‘al Hazor, Ba‘al Peor etc.
This was the norm in the world of religion. In a time when travel and communications were difficult, demanding adherents travel days or weeks to visit a temple to their deity was a lot to ask. Surely the gods would be pleased with a second, or multiple, temples to facilitate worship. With time, localized variations of cult practice or story would result.
A fine article by Nadav Na’aman of Tel Aviv University entitled In Search of the Temples of YHWH of Samaria and YHWH of Teman has linked these two expressions with other extrabibical usage and as well as references in Kings, Amos and Hosea to temples in the north at Bethel of Samaria and Beer-sheba of of Teman in the south. There Yahweh was still worshiped using the more ancient symbolism of a bull in those locations.
My interest in this topic of a regionalization of Yahweh came up when discussing the recent further centralization of the WT church organization. Anyone who has traveled learns that the JWs while generally united in loyalty to the WT headquarters display a surprisingly diversity in enforcement of rules and strictness of conformity. I wonder if one of the motivations for shifting to recorded media and lessening the teaching role of the local church leadership is to tighten ranks and control.
