C. F. Keil and Franz Delitzsch on 2 Kings 6:26

2Ki 6:26

As the king was passing by upon the wall to conduct the defence, a woman cried to him for help; whereupon he replied: אל־יושׁעך יי, “should Jehovah not help thee, whence shall I help thee? from the threshing-floor or from the wine-press?” It is difficult to explain the אל which Ewald (§355, b.) supposes to stand for אם לא. Thenius gives a simpler explanation, namely, that it is a subjective negation and the sentence hypothetical, so that the condition would be only expressed by the close connection of the two clauses (according to Ewald, §357). “From the threshing-floor or from the wine-press?” i.e., I can neither help thee with corn nor with wine, cannot procure thee either food or drink. He then asked her what her trouble was; upon which she related to him the horrible account of the slaying of her own child to appease her hunger, etc.
