Isaiah 36:27

Therefore their inhabitants were of small power, helpless before the invaders; they were dismayed and confounded, rendered powerless by terror; they were as the grass of the field and as the green herb, as the grass on the housetops, with but a thin layer of soil, and as corn blasted before it be grown up, such vegetation being unable to withstand even a moderate amount of blasting winds. The prophecy now turns directly against Sennacherib.
