2 Kings 7:5

And they rose up in the twilight, to go unto the camp of the Syrians,...., The dusk of the evening, or the evening twilight, as appears from 2 Kings 7:9,

and when they were come to the uttermost part of the camp of Syria; not the further part of it, but the edge or border of it nearest to them:

behold, there was no man there; no sentinel or guard, which they expected, and to whom they would have surrendered themselves.
