Albert Barnes Commentary 2 Kings 6:27

"And he said, If Jehovah do not help thee, whence shall I help thee? out of the threshing-floor, or out of the winepress?" — 2 Kings 6:27 (ASV)

If the Lord does not help - The translation in the text is decidedly better than the marginal rendering. Some prefer to render it: “No... let Jehovah help you. From where shall I help you?”

Out of the barnfloor ... - The king means that both were empty—that he no longer had any food in store; and therefore could not help the woman. Compare Hosea 9:2.
