The inscription, written in ink on clay, is the earliest yet found in Hebrew. It was discovered about 18 months ago in a dig at Khirbet Qeiyafa, near Emek Ha'ela. While it was quickly dated, its language remained uncertain until Prof. Gershon Galil was able to demonstrate that it was an early form of Hebrew - containing roots commonly found in Hebrew, but which are very rare in other Semitic languages.
A year and a half ago a 10th-century ostracon (pottery sherd with an ink inscription) was discovered at Khirbet Qeiyafa overlooking the Elah valley, south of Jerusalem and west of Hebron. The inscription has now been published and proves to be the earliest known example of Hebrew writing. It advocates care for widows and orphans and encourages the king-who at that time had the responsibility of curbing social inequality-to be involved in improving Israelite society. The inscription is similar in content to biblical scriptures such as Exodus 23:2, Psalm 72:4, Isaiah 1:17, and others, but according to the translator, Professor Gershon Galil of the Department of Biblical Studies at the University of Haifa, it is not copied from any one biblical text. The ostracon thus demonstrates that at least some of the biblical scriptures were composed hundreds of years before the dating of the composition of the Bible in much of contemporary academic research.
Since the inscription was clearly written by a scribe, Galil concludes: 'It can now be maintained that it was highly reasonable that during the 10th century BCE, during the reign of King David, there were scribes in Israel who were able to write literary texts and complex historiographies such as the books of Judges and Samuel.' He added that the complexity of the text, along with the impressive fortifications revealed at the site, refute theories that attempt to deny the existence of the Kingdom of Israel at that time.
Dr. Scott Stripling describes the ruins at Khirbet Qeifaya, where King Saul and David fought in battle against the Philistines at the Elah Valley. A pottery sherd with Hebrew writing was discovered here in 2008.
