Charles Ellicott 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 you. —This is right. The marginal rendering, “Let not the Lord help you!”—that is, “May the Lord destroy you!” would be possible in another context. Another rendering is, “No (that is, do not appeal to me), let the Lord help you!”

Out of the barnfloor. —Compare Hosea 9:2: The floor and the winepress shall not feed them, and the new wine shall fail in her. Jehoram, in the irony of despair, reminds the woman of what she well knows—namely, that the corn and wine, the staple foods of the time, are long since exhausted. The words, If the Lord does not help you, may be compared with 2 Kings 3:10, Alas! that the Lord has called, etc. The character of Jehoram is consistently drawn. But perhaps the point is: “Jehovah alone is the giver of corn and wine (Hosea 2:8–9). Appeal not to me for these.”
