HI Paul,
Yes I am aware of the Tel Dan Stele, I have researched it thouroughly and have to conclude that Biran and Naveh's arguments in favour of this being a reference to a historical David are less than convincing.
The most obvious problem is that in the Hebrew Bible 'House of David' is always written in two words 'Bet David' as do the references to contemporary dynastic names from Syria and Mesopotamia (Bit Adina, Bit Gusi and Bit Humriya).
The Tel Dan inscription does not have a word divider, the reference is to 'bytdwd', and other references with name combinations like this in the Hebrew Bible always refer to places. For example Bethel, Bethany and Bethlehem all refer to places so 'bytdwd' may refer to a place that was near Dan.
What I find strange for this period of Israel's history is that the Bible makes great claims for Saul, David and Solomon, they allegedly were very significant people who led vast armies and defeated many enemies, yet what do we find of their empires, an ambiguous reference in an inscription at Dan?
Maybe in the future more artefacts will be discovered but I find it surprising that, given the extensive excavations in Palestine, we still have no undisputed reference to any of these three Kings.
Brian.
