Jamieson, Fausset and Brown on Isaiah 22:13

13. Notwithstanding Jehovah's "call to mourning" (Is 22:12), many shall make the desperate state of affairs a reason for reckless revelry (Is 5:11, 12, 14; Jr 18:12; 1Co 15:32).

Is 22:15-25. Prophecy That Shebna Should Be Deposed from Being Prefect of the Palace, and Eliakim Promoted to the Office.

In Is 36:3, 22; 37:2, we find Shebna "a scribe," and no longer prefect of the palace ("over the household"), and Eliakim in that office, as is here foretold. Shebna is singled out as the subject of prophecy (the only instance of an individual being so in Isaiah), as being one of the irreligious faction that set at naught the prophet's warnings (Is 28:1-33:24); perhaps it was he who advised the temporary ignominious submission of Hezekiah to Sennacherib.
