Albert Barnes Commentary 2 Kings 14:26

"For Jehovah saw the affliction of Israel, that it was very bitter; for there was none shut up nor left at large, neither was there any helper for Israel." — 2 Kings 14:26 (ASV)

The affliction of Israel - This refers to what the Israelites had suffered for two reigns at the hands of the Syrians (2 Kings 10:32–33; 13:3, 7, 22).

There was not any shut up, nor any left - A phrase implying complete depopulation (see 1 Kings 14:10), but here meaning nothing more than extreme depression and weakness.
