Shouldn't I be concerned for Nineveh, that great city, in which are more than one hundred twenty thousand persons who can't discern between their right hand and their left hand; and also much cattle?"
Not only do the six miracles in each case cited here correspond in general pattern, but there is also the most remarkable correspondence in a number of specific instances.  In each instance, two of the supportive miracles are from above, two from the dead level, and two from beneath the earth's surface.  Note that in the case of the gourd vine and the earthquake, two of the dead level miracles, that each of them reached both above and below the surface of the earth.  The earthquake's high epicenter was nevertheless below the ground, but the mighty rocks which were cast up by the terrible force of it were heaped up above the surface of the earth, as any traveler in Jerusalem may still see.  Likewise, the gourd vine had its tap root going down below the surface, but the height of it reached up above Jonah's head.  This quality of being both above and below the surface requires both to be classified as surface wonders.
