E ora, scommetti con il mio signore, il re d'Assiria: io ti darò duemila cavalli, se tu sei in grado di procurarti dei cavalieri da mettere su di essi.

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.
