Henry Smith, Scott Lanser, and archeologist Dr. Scott Stripling have a round table discussion on ABR's most important artifiact ever found, an ancient curse tablet found on Mt Ebal in an altar that dates back to the time of Joshua. They talk about the Biblical context, wet sifting technology, analysis of the proto-alphabetic writing on the inside of the tablet, and how that writing on the inside is now the oldest Hebrew text ever found in Israel, and its implications.
