Charles Spurgeon Commentary 2 Kings 6:7-8

"And he said, Take it up to thee. So he put out his hand, and took it. Now the king of Syria was warring against Israel; and he took counsel with his servants, saying, In such and such a place shall be my camp." — 2 Kings 6:7-8 (ASV)

Of course, he wanted to keep it secret, and pounce upon Israel here and there without notice and so win an easy victory.
