Two discoveries announced after the end of Israel's 2005 excavation season may substantiate the biblical account of kings David and Solomon. And another recently announced finding sheds new light on the development of the early Christian church.

In July, slanting rays from the early morning sun drew archaeologists' attention to an inscription on a stone embedded in a 3,000-year-old wall at Tel Zayit, about 30 miles southwest of Jerusalem. On the excavation season's last day, work had started early to catch the best light for photographs. What the archaeologists almost missed turned out to be an abecedary—letters listed in alphabetical order—possibly the oldest version of the Hebrew alphabet now known.

"It represents a hinge in the development of the alphabet and the rise of literacy," says head archaeologist Ron Tappy of Pittsburgh Theological Seminary. The letter shapes appear to be transitional, between the forms of Canaanite/Phoenician and later Hebrew. "It does seem to indicate that there was a literate scribal class in this region of the country."

The building where archaeologists found the inscription has been dated around 950-900 B.C. Its architecture suggests centralized planning and leads Tappy to a further conclusion: "In the southern hills of Canaan, in the 10th century B.C., there was some sort of evolving patrimonial kingdom that we can attribute to King Solomon." Tappy's conclusion challenges arguments by some scholars that David and Solomon are more legend than fact, and that the biblical accounts of the early Israelite monarchy were written centuries later.
