So shall we come upon him in some place where he shall be
found
For such a numerous army, which would be spread abroad, could not well fail of finding him out, let him be in what lurking place he would; whereas he might lie concealed, and escape so small a number as twelve thousand men:
and we will light upon him as the dew falleth upon the ground;
whose drops are innumerable, and cover all the ground where they fall; and the phrase not only expresses their numbers, but the irresistible force they should come with, and the manner, secretly, unawares, opportunely; the Romans had a sort of soldiers, called from the dew "rorarii", who carried light armour, and fought first in the battle, from whence they had their name, because dew falls before it rains F14:
and of him, and of all the men that [are] with him, there shall not be
left so much as one;
so that for the future Absalom would sit easy upon the throne, there being none left to molest him.
