Isaiah 3:25

The sword. In coming judgments the men of Judah would fall by the sword of invading armies. It is impossible to say how many thousands in Judah perished at the hands of the Assyrians during the days of Isaiah. If over 200,000 men and women were taken captive at the time of Sennacherib’s invasion of 701, it is possible that the number slain in this, his first campaign, was even greater (see on 2 Kings 18:13). It should be noted, however, that Sennacherib is often given to exaggeration.

Thy mighty in the war. Sennacherib mentions the elite troops of Hezekiah falling into his hands. Undoubtedly many of the bravest soldiers perished and many others were taken captive to the far land of Assyria.
