2 Samuel 17:16

Now, therefore, send quickly and tell David, saying, offering him advice which he could not afford to ignore, Lodge not this night in the plains of the wilderness, near the fords on the west side of the river, but speedily pass over; lest the king be swallowed up, and all the people that are with him. There was always danger that an expedition might be sent against him before he had completed his plans and gotten ready to defend himself. He would be safer at any rate on the east side, where he might also find additional followers.
