2 Kings 6:6

No doubt there is something startling in the trivial character of this miracle, and of the few others which resemble it. But, inasmuch as we know very little as to the laws which govern the exercise of miraculous powers, it is possible that they may be so much under their possessor’s control that he can exercise them, or not exercise them, at pleasure. And it may depend on his discretion whether they are exercised in important cases only, or in trivial cases also. Elisha had evidently great kindness of heart. He could not see a grief without wishing to remedy it. And it seems as if he had sometimes used his miraculous power in pure good nature, when no natural way of remedying an evil presented itself.
