In Isaiah 22 the prophet rails in God's name against the excesses of the officials in King Hezekiah's palace. In 1870 the famous French diplomat, scholar and archaeologist Charles Clermont-Ganneau excavated a partially destroyed tomb high up on the cliff overlooking the Kidron Valley and the City of David in Jerusalem. Over the entrance to the rock-cut burial chamber was an inscription that, unfortunately, he was unable to decipher. Was this the tomb of Shebna the high court official mentioned in Isaiah who is, literally, 'over the house' or in charge of the palace (often identified as the treasurer) and who was castigated by the prophet for building himself such an elaborate tomb on the cliff?
