Jacob was above the average in intellect, with the oriental aptitude for languages. He spoke five fluently, with a partial knowledge of several others. He was interested in archaeology, and the year before we came to Jerusalem he discovered the Siloam Inscription... His imagination was fired by learning about the subterranean tunnel in the Ophal Hill that had been excavated by King Hezekiah to bring water inside the threatened city... It is supposed to be haunted by a dragon or genie... Nevertheless, Jacob determined to explore the tunnel... Jacob, feeling his way, suddenly was conscious that the chisel marks had changed and were now going from left to right. He realized he must be in the exact place where the King's workmen had met under the city. Carefully he felt all around the walls, and was certain that his fingers detected an inscription chiseled in the stone.
