Shebna: tender youth, "treasurer" over the house in the reign of Hezekiah, i.e., comptroller or governor of the palace. On account of his pride he was ejected from his office, and Eliakim was promoted to it (Isaiah 22:15-25). He appears to have been the leader of the party who favoured an alliance with Egypt against Assyria. It is conjectured that "Shebna the scribe," who was one of those whom the king sent to confer with the Assyrian ambassador (2 Kings 18:18,26,37; 19:2; Isaiah 36:3,11,22; 37:2), was a different person.
