Genesis 1:28

28. And God blessed them This blessing of God may be regarded as the source from which the human race has flowed. And we must so consider it not only with reference to the whole, but also, as they say, in every particular instance. For we are fruitful or barren in respect of offspring, as God imparts his power to some and withholds it from others. But here Moses would simply declare that Adam with his wife was formed for the production of offspring, in order that men might replenish the earth. God could himself indeed have covered the earth with a multitude of men; but it was his will that we should proceed from one fountain, in order that our desire of mutual concord might be the greater, and that each might the more freely embrace the other as his own flesh. Besides, as men were created to occupy the earth, so we ought certainly to conclude that God has mapped, as with a boundary, that space of earth which would suffice for the reception of men, and would prove a suitable abode for them. Any inequality which is contrary to this arrangement is nothing else than a corruption of nature which proceeds from sin. In the meantime, however, the benediction of God so prevails that the earth everywhere lies open that it may have its inhabitants, and that an immense multitude of men may find, in some part of the globe, their home. Now, what I have said concerning marriage must be kept in mind; that God intends the human race to be multiplied by generation indeed, but not, as in brute animals, by promiscuous intercourse. For he has joined the man to his wife, that they might produce a divine, that is, a legitimate seed. Let us then mark whom God here addresses when he commands them to increase, and to whom he limits his benediction. Certainly he does not give the reins to human passions, but, beginning at holy and chaste marriage, he proceeds to speak of the production of offspring. For this is also worthy of notice, that Moses here briefly alludes to a subject which he afterwards means more fully to explain, and that the regular series of the history is inverted, yet in such a way as to make the true succession of events apparent. The question, however, is proposed, whether fornicators and adulterers become fruitful by the power of God; which, if it be true, then whether the blessing of God is in like manner extended to them? I answer, this is a corruption of the Divine institute; and whereas God produces offspring from this muddy pool, as well as from the pure fountain of marriage, this will tend to their greater destruction. Still that pure and lawful method of increase, which God ordained from the beginning, remains firm; this is that law of nature which common sense declares to be inviolable.

Subdue it He confirms what he had before said respecting dominion. Man had already been created with this condition, that he should subject the earth to himself; but now, at length, he is put in possession of his right, when he hears what has been given to him by the Lord: and this Moses expresses still more fully in the next verse, when he introduces God as granting to him the herbs and the fruits. For it is of great importance that we touch nothing of God’s bounty but what we know he has permitted us to do; since we cannot enjoy anything with a good conscience, except we receive it as from the hand of God. And therefore Paul teaches us that, in eating and drinking we always sin, unless faith be present, (Romans 14:23.) Thus we are instructed to seek from God alone whatever is necessary for us, and in the very use of his gifts, we are to exercise ourselves in meditating on his goodness and paternal care. For the words of God are to this effect: ‘Behold, I have prepared food for thee before thou wast formed; acknowledge me, therefore, as thy Father, who have so diligently provided for thee when thou wast not yet created. Moreover, my solicitude for thee has proceeded still further; it was thy business to nurture the things provided for thee, but I have taken even this charge also upon myself. Wherefore, although thou art, in a sense, constituted the father of the earthly family, it is not for thee to be overanxious about the sustenance of animals.’
