isaiah 22:2 Thou that art full of stirs, a tumultuous city, a joyous city: thy slain men are not slain with the sword, nor dead in battle. - Free Bible Online

      2. art--rather, "wert"; for it could not now be said to be "a joyous city" (Isa 32:13). The cause of their joy (Isa 22:13) may have been because Sennacherib had accepted Hezekiah's offer to renew the payment of tribute, and they were glad to have peace on any terms, however humiliating (2Ki 18:14-16), or on account of the alliance with Egypt. If the reference be to Zedekiah's time, the joy and feasting are not inapplicable, for this recklessness was a general characteristic of the unbelieving Jews (Isa 56:12).
      not slain with the sword--but with the famine and pestilence about to be caused by the coming siege (La 4:9). MAURER refers this to the plague by which he thinks Sennacherib's army was destroyed, and Hezekiah was made sick (Isa 37:36; 38:1). But there is no authority for supposing that the Jews in the city suffered such extremities of plague at this time, when God destroyed their foes. BARNES refers it to those slain in flight, not in open honorable "battle"; Isa 22:3 favors this.
