A 12th century potsherd containing Canaanite text was recently unearthed in ruins of a temple at the biblical site of Lachish. It's the first Late Bronze Age Canaanite inscription discovered in over 30 years, and contains the oldest precursor to the letter 'S' ever found. The discovery will provide important information about the development of the alphabet. In the Bible, Lachish grew to be an important fortified city of the Israelite monarchy before being besieged by Sennacherib's army in 701 BC, an event alluded to in 2 Kings 18:13-14 and Isaiah 36:2.
