Und nun versuch’ es mit meinem Herrn, dem König von Assyrien. Ich will dir zweitausend Rosse geben, ob du dir Reiter darauf setzen kannst?
From David to Destruction
Another approach may be developed based on the fact that, from a purely secular-pragmatic perspective, Ravshakeh is entirely correct. The Assyrians were masters of war and masters of breaking sieges. Their quality and quantity of soldiers were unmatched. As Ravshakeh notes in Melachim II 18:23-24, the Jewish army cannot compete even with a small subdivision of the Assyrian military.
