Albert Barnes Commentary 2 Kings 7:5

"And they rose up in the twilight, to go unto the camp of the Syrians; and when they were come to the outermost part of the camp of the Syrians, behold, there was no man there." — 2 Kings 7:5 (ASV)

The twilight—The evening twilight (see 2 Kings 7:9).

The uttermost part of the camp—The extreme boundary of the camp toward the city, not its furthest or most distant portion. Compare 2 Kings 7:8.
