Isaiah 3:7

7.In that day shall he swear. The word swear expresses an absolute and vehement refusal; for frequently he who at first excuses himself, or declares that he will not do it, at length yields to entreaty; but he who, in refusing, employs an oath, shuts out all hope, because he gives them to understand that his purpose is firm and decided. Perhaps, too, the phrase in that day, means “immediately, without any delay, and without long consultation;” but as it may also be viewed demonstratively, ( δεικτικῶς,) as pointing out more fully the time of the calamity, I do not express a strong opinion. The general meaning is obvious, that their ruinous condition will be past remedy.

As to the word חבש, (chobesh,) though commentators differ in their interpretation of it, yet I cheerfully concur with those who think that the metaphor is here borrowed from surgeons; (57) for nothing can more fully meet the case. It is as if one, to whom application had been made to heal a sick man, should declare that he has no skill in the art of healing, or that the disease is too inveterate to admit of being cured.

The next copulative ו, (vau,) means for; as if he had said, “And undoubtedly I have not ability to do so.” (58) His meaning therefore is, that the state of affairs will be so desperate, that no man, even when matters are at the worst, will venture to take measures for their defense.
