Yahweh God prepared a vine, and made it to come up over Jonah, that it might be a shade over his head, to deliver him from his discomfort. So Jonah was exceedingly glad because of the vine.
Jonah tells us that a gourds or a cucumber, or an ivy, was prepared by the Lord. There is no doubt but that this shrub grew in a manner unusual, that it might be a cover to the booth of Jonah. So I view the passage. But God, we know, approaches nature, whenever he does anything beyond what nature is: this is not indeed always the case; but we generally find that God so works, as that he exceeds the course of nature, and yet from nature he does not wholly depart. For when in the desert he intended to collect together a great quantity of quails, that he might give meat to the people, he raised wind from the east, (Numbers 11:31.) How often the winds blew without bringing such an abundance of birds? It was therefore a miracle: but yet God did not wholly cast aside the assistance of nature; hence he made use of the wind; and yet the wind could not of itself bring these birds. So also in this place, God had chosen, I have no doubt, a herb, which soon ascended to a great height, and yet far surpassed the usual course of nature. In this sense, then, it is that God is said to have prepared the קיקיון, kikiun, (56) and to have made it to ascend over Jonah’s head, that it might be for a shade to his head and free him from his distress.
