We will light upon him as the dew falleth upon the ground Plenteously, suddenly, irresistibly, and on all sides; for so the dew falls. This is very beautiful and expressive. “The dew in Palestine, as in several other climates, falls fast and sudden; and is therefore an apt emblem of an active and expeditious soldiery. And it was, perhaps, for this reason that the Romans called their light armed forces, rorarii. The dew falls upon every spot of the earth; not a blade of grass escapes it. A numerous army resembles it in this respect; it is able to search everywhere.” Delaney.
