For as the rain and the snow come down from heaven,

and do not return there until they have watered the earth,

making it bring forth and sprout,

giving seed to the sower and bread to the eater,


so shall my word be that goes out from my mouth;

it shall not return to me empty,

but it shall accomplish that which I purpose,

and succeed in the thing for which I sent it.



For you shall go out in joy,

and be led back in peace;

the mountains and the hills before you

shall burst into song,

and all the trees of the field shall clap their hands.


Instead of the thorn shall come up the cypress;

instead of the brier shall come up the myrtle;

and it shall be to the Lord for a memorial,

for an everlasting sign that shall not be cut off.

10. Surely, as the rain cometh down. After having spoken of God’s tender affection and inconceivable forbearance towards us, he again brings forward the promises, that, by relying on them, we may banish all doubt of being free from every danger. It would be of little avail to speak to us about the nature or the secret purpose of God, if we were not reminded of “the word,” by which he reveals himself. Now, God speaks openly to us, so that it is unnecessary to make longer inquiry. We must therefore come to the word, in which his will is declared without obscurity, provided that all our senses are confined within those limits; for otherwise we remain in suspense, and doubt what he has determined concerning us, even though the Lord declare a thousand times that he is altogether unlike men; for, although men acknowledge this, yet they wish to be certain about themselves and their salvation. 8989     “Lesquels desirent (s’ils veulent dire la verite) estre certains de leur salut, et que ce qu’ils deviendront.” “Who desire (if they are willing to tell the truth) to be certain about their salvation, and what shall become of them.” For this reason we ought carefully to observe the order which is followed by the Prophet. Thus also Moses recalled the people to the knowledge of God. “Say not thou, Who shall ascend to heaven? or, Who shall descend into the deep? The word is nigh, in thy mouth and in thy heart.” (Deuteronomy 30:12) “That is,” saith Paul, “the word of faith which we preach.” (Romans 10:8)

He employs a comparison drawn from daily experience and wonderfully appropriate; for, if we see great efficacy in the rain, which waters and fertilizes the earth, much greater efficacy will God display in his word. The rain is transitory and liable to corruption; but the word is eternal, unchangeable, and incorruptible, and cannot, like the rain, vanish away.

That we may more fully understand the Prophet’s words, we must keep in view the end at which he aims. Men doubt if God will actually perform what he promises in his word; for we look upon the word, as if it were suspended in the air and had no effect. How shocking this is, he demonstrates from the very course of nature; for it is in the highest degree unreasonable to ascribe less to the word than to a dumb creature; and therefore he teaches us, that his word never fails of its effect. Some understand this to mean that the preaching of the Gospel is never unprofitable, but always produces some fruit. This is true in itself; for the Lord worketh by his Spirit, and “giveth increase,” (1 Corinthians 3:7) so that the labor of his servants is not unproductive. But the Prophet’s meaning was different; namely, that God does not speak in vain or scatter his promises into the air, but that we shall actually receive the fruit of them, provided that we do not prevent it by our unbelief.

But watereth the earth, and causeth it to bring forth. He mentions two effects produced by the watering of the rain, which fertilizes the earth; first, that men have abundance of food for their support; and secondly, that they have seed for procuring a crop in the following year. If therefore in things of a transitory nature the power of God is so great, what must we think of the word? 9090     “These words depend on what goes before, and their meaning may thus be briefly stated. Let not the people refuse to believe that a wicked man, after having committed great crimes, shall suddenly be saved. For my thoughts are not as the thoughts of men; and as far as heaven is distant from the earth, so are my thoughts separated from the thoughts of men. I am most merciful and ready to forgive. Would you wish to have another metaphor? As the rain and snow come down from heaven, and do not return thither, but water and refresh the earth, and cause it to bring forth various productions, that the corn-fields may produce abundance of bread for the use of men; so the word of my promise, which I have promised once and again, and which hath gone out of my mouth, shall not be void, but all shall be actually fulfilled.” ­ Jerome.

11. So shall my word be. The word goeth out of the mouth of God in such a manner that it likewise “goeth out of the mouth” of men; for God does not speak openly from heaven, but employs men as his instruments, that by their agency he may make known his will. But the authority of the promises is more fully confirmed, when we are told that they proceed from the sacred mouth of God. Although, therefore, he brings forward witnesses from the earth, he declares that all that they have promised shall be ratified and sure; and, in order to impress more deeply on the minds of men the power and efficacy of preaching, he declares that he does not cast that precious seed at random, but appoints it for a fixed purpose, and consequently that we ought to entertain no doubt as to the effect; for there is nothing to which mortals are more prone than to judge of God from themselves so as to withhold belief from his voice.

This doctrine must be frequently repeated and inculcated, that we may know that God will do what. he hath once spoken. For this reason, when we hear the promises of God, we ought to consider what is his design in them; so that, when he promises the free pardon of our sins, we may be fully assured that we are reconciled through Christ. But, as the word of God is efficacious for the salvation of believers, so it is abundantly efficacious for condemning the wicked; as Christ also teacheth, “The word which I have spoken, that shall judge him at the last day.”

12. Therefore ye shall go out with joy. The Prophet concludes the subject of this chapter; for, when he spoke of the mercy of God, his object was, to convince the Jews that the Lord would deliver them. He now applies to his purpose what was contained in his discourse concerning the infinite goodness of God, and shows that his thoughts are very unlike the thoughts of men. And the true way of teaching is this, that we should apply general statements for present use. Finally, he treats of the restoration of the people, which depended on the undeserved mercy of God.

The mountains and hills shall break out before you. By “the mountains and hills” he means that everything which they shall meet in the journey, though in other respects it be injurious, shall aid those who shall return to Jerusalem. They are metaphors, by which he shows that all the creatures bow to the will of God, and rejoice and lend their aid to carry on his work. He alludes to the deliverance from Egypt, (Exodus 14:22) as is customary with the Prophets; for thus is it described by the Psalmist, “The mountains leaped like rams, and the hills like lambs. What ailed thee, O sea, that thou fleddest, and Jordan, (Joshua 3:16) that thou wast driven back? (Psalm 114:4, 5) For the restoration of the Church may be regarded as a renovation of the whole world, and in consequence of this, heaven and earth are said to be changed, as if their order were reversed. But all this depended on former predictions, by which they had received a promise of their return.

13. Instead of the bramble 9191     “Instead of the thorn.” ­ Eng. Ver. shall come up the fir-tree. He still extols the power of God, which would be visible in the restoration of the people; for he shows that the change will be such that they shall have an easy road to return. Some explain it allegorically, and suppose that by “brambles” are meant men who wish to do injury, and who inflict wounds on others, and that these shall be “fir­trees,” that is, trees that bear fruit and that are useful to their neighbors; but in expositions of that kind ingenuity is carried to excess. When they say that these things relate to the kingdom of Christ, and on that account ought to be understood in a spiritual sense, I agree with them; for the Prophet begins with the departure from Babylon, and includes the whole condition of the Church, till Christ was manifested to the world. But the propriety of that allegory must not therefore be admitted; for he speaks of the departure from Babylon, and, in order to open it up for his people, he says that he will remove every obstacle, and will supply them with everything necessary, so that they shall suffer no inconvenience. In like manner, when Christ promises the benefit of redemption, he likewise takes away everything that would injure or retard, and even turns those things to a different and totally opposite purpose, that from them also they may receive some benefit. All things (Romans 8:28) tend to the advantage of believers, and those things which would otherwise be injurious and destructive, are employed by God as remedies to purify them, that they may not be devoted to the world, but may become more ready and cheerful in the service of their Master. 9292     “Au service de leur maistre.”

And shall be to Jehovah for a name. When he says that it shall be to God “for a name,” he shows what is the design of the restoration of the Church. It is, that the name of God may be more illustrious among men, and that the remembrance of him may flourish and be maintained. On this account he adds that it shall be a perpetual sign, that is, a monument, and, as we commonly say, a memorial; and although, amidst these tempests, the Church be tossed and agitated in various ways, yet, because the Lord wishes that the remembrance of his name may be everlasting, he will guard and defend her.
