Israeli archeologist, Eilat Mazar, has dug up a piece of ceramic in the City-of-David part of Jerusalem. It has an inscription on it and it is old, from at least the 9th or maybe even the 10th or 11th century B.C.E. The discovery is new and so we have no hard conclusions There will be ongoing discussions for years, probably.
To see several preliminary ideas about this, see here.
What amazes me is that we keep finding really ancient artifacts.
