Adam Clarke on 2 Kings 6:10

Sent to the place - To see if it were so. But the Vulgate gives it quite a different turn: Misit rex Israel ad locum, et praeoccupavit eum. The king of Israel sent previously to the place, and took possession of it; and thus the Syrians were disappointed. This is very likely, though it is not expressed in the Hebrew text. The prophet knew the Syrians marked such a place; he told the king of Israel, and he hastened and sent a party of troops to pre-occupy it; and thus the Syrians found that their designs had been detected.
