Genesis 2:1-2
1 Thus the heavens and the earth were finished, and all the host of them.
2 And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made.
3 And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.
“Thus the heavens and the earth were finished.” Moses summarily repeats that in six days the fabric of the heaven and the earth was completed. The general division of the world is made into these two parts, as has been stated at the commencement of the first chapter. But he now adds, “all the host of them,” by which he signifies that the world was furnished with all its garniture. This epilogue, moreover, with sufficient clearness entirely refutes the error of those who imagine that the world was formed in a moment; for it declares that an end was only at length put to the work on the sixth day. Instead of “host” we might not improperly render the term “abundance;” for Moses declares that this world was in every sense completed, as if the whole house were well supplied and filled with its furniture. The heaven, without the sun, and moon, and stars, would be an empty and dismantled palace: if the earth were destitute of animals, trees, and plants, that barren waste would have the appearance of a poor and deserted house. God, therefore, did not cease from the work of the creation of the world till he had completed it in every part, so that nothing should be wanting to its suitable abundance.
But he now adds, “all the host of them,” by which he signifies that the world was furnished with all its garniture.
“And he rested on the seventh day.” The question may not improperly be put, what kind of rest this was. For it is certain that inasmuch as God sustains the world by his power, governs it by his providence, cherishes and even propagates all creatures, he is constantly at work. Therefore that saying of Christ is true, that the Father and he himself had worked from the beginning hitherto, because, if God should but withdraw his hand a little, all things would immediately perish and dissolve into nothing, as is declared in Psalm 104:29. And indeed God is rightly acknowledged as the Creator of heaven and earth only whilst their perpetual preservation is ascribed to him. The solution of the difficulty is well known, that God ceased from all his work, when he desisted from the creation of new kinds of things. But to make the sense clearer, understand that the last touch of God had been put, in order that nothing might be wanting to the perfection of the world. And this is the meaning of the words of Moses, From all his work which he had made; for he points out the actual state of the work as God would have it to be, as if he had said, then was completed what God had proposed to himself. On the whole, this language is intended merely to express the perfection of the fabric of the world; and therefore we must not infer that God so ceased from his works as to desert them, since they only flourish and subsist in him. Besides, it is to be observed, that in the works of the six days, those things alone are comprehended which tend to the lawful and genuine adorning of the world.
Moses is not considering God as armed for the punishment of the sins of men; but as the Artificer, the Architect, the bountiful Father of a family who has omitted nothing essential to the perfection of his edifice.
It is subsequently that we shall find God saying, “Let the earth bring forth thorns and briers,” by which he intimates that the appearance of the earth should be different from what it had been in the beginning. But the explanation is at hand; many things which are now seen in the world are rather corruption of it than any part of its proper furniture. For ever since man declined from his high original, it became necessary that the world should gradually degenerate form its nature. We must come to this conclusion respecting the existence of fleas, caterpillars, and other noxious insects. In all these, I say, there is some deformity of the world, which ought by no means to be regarded as in the order of nature, since it proceeds rather from the sin of man than from the hand of God. Truly these things were created by God, but by God as an avenger. At the present time, when we look upon the world corrupted, and as if degenerated from its original creation, let that expression of Paul recur to our mind, that the creature is liable to vanity, not willingly, but through our fault, (Rom. 8:20) and thus let us mourn, being admonished of our just condemnation. In this place, however, Moses is not considering God as armed for the punishment of the sins of men; but as the Artificer, the Architect, the bountiful Father of a family who has omitted nothing essential to the perfection of his edifice.
