Isaiah 33:21

But there - In Jersalem; or in his church, of which Jerusalem was the emblem. The glorious Lord - Lowth renders it, ‘The glorious name of Yahweh,’ שׁם shâm to be a noun, as if it were pointed שׁם shēm. So the Syriac and the Septuagint read it. The word ‘glorious’ (אדיר 'adiyr) means magnificent; denoting that Yahweh would manifest himself there as magnificent or great in the destruction of his enemies, and in the protection of his people.

Jerusalem had not the advantage of a river; Jehovah will be as one to it, affording all the advantages, without any of the disadvantages of one. galley with oars--war vessels of a long shape, and propelled by oars; merchant vessels were broader and carried sail. gallant--same Hebrew word as for "glorious," previously; "mighty" will suit both places; a ship of war is meant.

THIS prophecy was uttered when the city of Jerusalem was reduced to the direst extremity. The Assyrian hosts threatened the city with utter destruction. Rabshakeh, a fitting herald for his tyrannical master, had advanced to inspect the walls while Sennacherib tarried at Lachish. False to all treaties, the heavy sum paid down by Hezekiah could not ensure the promised mercy from the ferocious despot. The treasuries of the city were exhausted, and therefore no further attempt in that direction could be made. No help could be looked for from any other nation.

Even Egypt was in deadly fear of the great power of Nineveh. The Assyrians were strong as lions, and cruel as evening wolves. No nation had ever equaled them in remorseless and wanton cruelty. Punishments the most horrible were constantly executed upon those whom they vanquished. Impalement, flaying alive, and piercing out the eyes were their ordinary amusements after the close of battle. Look at the stones disinterred from Nineveh, and you will see engraved there by themselves memorials of the horrible barbarities which they constantly perpetrated. Sennacherib's army was exceedingly great. It had already stormed many cities. Arphad and Sepharvaim, Hamath and Samaria had fallen an easy spoil—cities that were surrounded by rivers had been defeated by diverting the current and so drying up the streams. Or else by using galleys with oars, the Assyrian monarch had reached the walls and applied the scaling ladders. The army was so well equipped, so numerous, and so thoroughly well supplied with all munitions of war, that there was not the slightest hope of the escape of Jerusalem except by Divine power.

The glorious Lord “The glorious name of Jehovah” - I take שם shem for a noun, with the Septuagint and Syriac. See Psa 20:1; Pro 18:10.
