The Origins of the Divine Name

The earliest references we have to a deity that goes by that name, the Tetragrammaton Adonai, come from the second half of the ninth century BCE. The Maysha inscription refers directly to the god of Israel as Adonai in talking about one of their battles between Moab and Israel. And then we have discussion of some of the kings of Israel and specifically of the Amride dynasty. We don't have a direct reference to the deity themselves in the other two inscriptions but what we do have are references to Israelite or Judahite kings who have names that have Yauistic Theophoric elements.
