Calvin's Take on Jonah (4:6-8)

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 vine 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.
But it is said afterwards that a worm was prepared. We see here also, that what seemed to happen by chance was yet directed by the hidden providence of God. Should any one say, that what is here narrated does not commonly happen, but what once happened; to this I answer, -- that though God then designed to exhibit a wonderful example, worthy of being remembered, it is yet ever true that the gnawing even of worms are directed by the counsel of God, so that neither a herb nor a tree withers independently of his purpose. The same truth is declared by Christ when he says, that without the Father's appointment the sparrows fall not on the ground, ( Matthew 10:29) Thus much as to the worm.
It is now added, that when the sun arose the day following, a wind was prepared. We here learn the same thing, -- that winds do not of themselves rise, or by chance, but are stirred up by a Divine power. There may indeed be found causes in nature why now the air is tranquil, and then it is disturbed by winds; but God's purpose regulates all these intermediate causes; so that this is ever true -- that nature is not some blind impulse, but a law settled by the will of God. God then ever regulates by his own counsel and hand whatever happens. The only difference is, that his works which flow in the usual course have the name of nature; and they are miracles and retain not the name of nature, when God changes their wonted course; but yet they all proceed from God as their author. Therefore with regard to this wind, we must understand that it was not usual or common; and yet that winds are daily no less stirred up by God's providence than this wind of which Jonah speaks. But God wrought then, so to speak, beyond the usual course of nature, though he daily preserves the regular order of nature itself.
Let us now see why this whole narrative has been set down. Jonah confesses that he rejoiced with great joy, when he was sheltered from the extreme heat of the sun: but when the shrub withered, he was touched with so much grief that he wished to die. There is nothing superfluous here; for Jonah shows, with regard to his joy and his grief, how tender he was and how susceptible of both. Jonah here confesses his own sensibility, first by saying that he greatly rejoiced, and then by saying that he was so much grieved for the withered shrub, that through weariness of life he instantly desired death. There is then here an ingenuous confession of weakness; for Jonah in a very simple manner has mentioned both his joy and his grief. But he has distinctly expressed the vehemence of both feelings, that we might know that he was led away by his strong emotions, so that in the least things he was either inflamed with anger, or elated with joy beyond any bounds. This then was the case with him in his grief as well as in his joy. But he does not say that he prayed as before; but he adopts the word which signifies to desire or wish. He desired, it is said, for his soul that he might die. It is hence probable that Jonah was so overwhelmed with grief that he did not lift up his heart to God; and yet we see that he was not neglected by God...
