Make thee an ark of gopher wood. Here follows the command to build the ark, in which God wonderfully proved the faith and obedience of his servant. Concerning its structure, there is no reason why we should anxiously inquire, except so far as our own edification is concerned. First, the Jews are not agreed among themselves respecting the kind of wood of which it was made. Some explain the word gopher to be the cedar; others, the fir-tree; others, the pine. They differ also respecting the stories; because many think that the sink was in the fourth place, which might receive the refuse and other impurities. Others make five chambers in a triple floor, of which they assign the highest to the birds. There are those who suppose that it was only three stories in height; but that these were separated by intermediate divisions. Besides, they do not agree about the window: to some it appears that there was not one window only, but many. Some say they were open to receive air; but others contend that they were only made for the sake of light, and therefore were covered over with crystal, and lined with pitch. To me it seems more probable, that there was only one, not cut out for the sake of giving light; but to remain shut, unless occasion required it to be opened, as we shall see afterwards. Further, that there was a triple story, and rooms separated in a manner to us unknown. The question respecting its magnitude is more difficult. For, formerly, certain profane men ridiculed Moses, as having imagined that so vast a multitude of animals was shut up in so small a space; a third part of which would scarcely contain four elephants. Origin solves this question, by saying that a geometrical cubit was referred to by Moses, which is six times greater than the common one; to whose opinion Augustine assents in his fifteenth book on the City of God,' and his first book of Questions on Genesis.' I grant what they allege, that Moses, who had been educated in all the science of the Egyptians, was not ignorant of geometry; but since we know that Moses everywhere spoke in a homely style, to suit the capacity of the people, and that he purposely abstained from acute disputations, which might savor of the schools and of deeper learning; I can by no means persuade myself, that, in this place, contrary to his ordinary method, he employed geometrical subtlety. Certainly, in the first chapter, he did not treat scientifically of the stars, as a philosopher would do; but he called them, in a popular manner, according to their appearance to the uneducated, rather than according to truth, "two great lights." Thus we may everywhere perceive that he designates things, of every kind by their accustomed names. But what was then the measure of the cubit I know not; it is, however, enough for me, that God (whom, without controversy, I acknowledge to be the chief builder of the ark) well knew what things the place which he described to his servant was capable of holding. If you exclude the extraordinary power of God from this history, you declare that mere fables are related. But, by us, who confess that the remains of the world were preserved by an incredible miracle, it ought not to be regarded as an absurdity, that many wonderful things are here related, in order that hence the secret and incomprehensible power of God, which far surpasses all our senses, may be the more clearly exhibited. Porphyry or some other caviller, [1] may object, that this is fabulous, because the reason of it does not appear; or because it is unusual; or because it is repugnant to the common order of nature. But I make the rejoinder; that this entire narration of Moses, unless it were replete with miracles would be colds and trifling, and ridiculous. He, however, who will reflect aright upon the profound abyss of Divine omnipotence in this history, will rather sink in reverential awe, than indulge in profane mockery. I purposely pass over the allegorical application which Augustine makes of the figure of the ark to the body of Christ, both in his fifteenth book of The City of God,' and his twelfth book against Faustus; because I find there scarcely anything solid. Origin still more boldly sports with allegories: but there is nothing more profitable, than to adhere strictly to the natural treatment of things. That the ark was an image of the Church is certain, from the testimony of Peter, (1-Peter 3:21;) but to accommodate its several parts to the Church, is by no means suitable, as I shall again show, in its proper place.

1 - "Hoc Porphyrius, vel quispiam alius canis, fabulosum esse obganniet." Throughout the above passage, Calvin takes for granted, that there was a miracle, when a close examination would have convinced him that there was none. It has only required the use of a little arithmetic, and common sense, to prove that the ark was more than sufficient to contain all the creatures which Noah was commanded to bring into it, as well as provision for the whole time of their residence in it. -- See Wells' Geography of the Old Test., chap. 11. -- Ed.

Make thee an ark - תבת tebath, a word which is used only to express this vessel, and that in which Moses was preserved, Exodus 2:3, Exodus 2:5. It signifies no more than our word vessel in its common acceptation - a hollow place capable of containing persons, goods, etc., without any particular reference to shape or form.
Gopher wood - Some think the cedar is meant; others, the cypress. Bochart renders this probable, 1. From the appellation, supposing the Greek word κυπαρισσος, cypress, was formed from the Hebrew גפר, gopher; for take away the termination ισσος, and then gopher and κυπαρ will have a near resemblance. 2. Because the cypress is not liable to rot, nor to be injured by worms. 3. The cypress was anciently used for ship-building. 4. This wood abounded in Assyria, where it is probable Noah built the ark. After all, the word is of doubtful signification, and occurs nowhere else in the Scriptures. The Septuagint render the place, εκ ξυλων τετραγωνων, "of square timber;" and the Vulgate, de lignis laevigatis, "of planed timber;" so it is evident that these translators knew not what kind of wood was intended by the original. The Syriac and Arabic trifle with the passage, rendering it wicker work, as if the ark had been a great basket! Both the Targums render it cedar; and the Persian, pine or fir.

Make thee an ark of Gopher wood,.... It is not called a ship, for it was not made for sailing to any distant parts, but an ark or chest, being like one, flat bottomed, and ridged and sloping upwards, and was made for floating on the waters for a little way. So Lucian (c), and other Heathen writers, call it "an ark" or "chest": this was made of "Gopher wood", which all the Targums, and the more ancient Rabbins, understand of cedar wood; some the box tree, as the Arabic version; others, the pine; others, fir; the Mahometans say it was the Indian plane tree; and others, the turpentine tree: but the cypress tree bids fairest to be the wood of which, the ark was made, as Fuller (d), Bochart (e), and others (f) have shown; that being nearest to "Gopher" in sound, and being a wood very durable and incorruptible, and fit for shipping. Alexander made a navy of cypress trees in the groves and gardens about Babylon, as Strabo (g) relates: where this ark was made, is not easy to say: some think in Palestine; others, near Mount Caucasus, on the borders of India; others, in China: but it is most likely it was near the garden of Eden, where Noah lived, and not far from Ararat, where the ark rested. Bochart (h) conjectures, that "Gopher" is the name of the place where it was made, as well as of the wood of which it was made; and that it might be Cupressetum or Cyparisson, which Strabo (i) places in Assyria. How long Noah was building the ark is variously conjectured: a Jewish (k) writer says fifty two years; and an Arabic writer (l) an hundred years; others think Noah was building it the whole one hundred and twenty years (m), the time of God's longsuffering and forbearance, which some conclude from 1-Peter 3:20 but though it would require not a few years to build such a vessel, and prepare everything necessary for the use of it, yet one would think it should not take so many years as the least account gives unto it: it may be observed, the order is, "make thou", or "for thyself" (n); for thy use and benefit, for the saving of thyself and family, as well as for the preservation of the several creatures which were for the service of him and his posterity:
rooms shalt thou make in the ark; or "nests" (o); little apartments, and many of them for the several creatures, and for their provisions, as well as for Noah and his family. The Targum of Jonathan gives us the number of them, paraphrasing the words thus,"one hundred and fifty cells shalt thou make for the ark on the left hand, and ten apartments in the middle to put food in, and five cabins on the right, and five on the left:"
and shalt pitch it within and without with pitch; it was pitched without to keep out the waters, and that they might more easily slide off, and to preserve the ark from being eat with worms, or hurt with the wind and sun; and it was pitched within, to take off the ill smell that might arise from the several creatures, as well as for the better security of the ark. Some take it to be bitumen, a sort of clay or slime like pitch, such as was used at the building of Babel, and of the walls of Babylon. De Dieu conjectures it was that kind of bitumen which the Arabs calls Kaphura, which agrees in sound with the word here used; but why not the pitch of the pine tree, or the rosin of the cypress tree, and especially the latter, if the ark was made of the wood of it (p)?

Make thee an ark--ark, a hollow chest (Exodus 2:3).
gopher wood--probably cypress, remarkable for its durability and abounding on the Armenian mountains.
rooms--cabins or small cells.
pitch it within and without--mineral pitch, asphalt, naphtha, or some bituminous substance, which, when smeared over and become hardened, would make it perfectly watertight.

I will destroy them with the earth, but make thee an ark - I will take care to preserve thee alive. This ark was like the hulk of a ship, fitted not to sail upon the waters, but to float waiting for their fall. God could have secured Noah, by the ministration of angels without putting him to any care or pains, but he chose to employ him in making that which was to be the means of his preservation, both for the trial of his faith and obedience, and to teach us that none shall be saved by Christ, but those only that work out their salvation; we cannot do it without God, and he will not without us: both the providence of God and the grace of God crown the endeavours of the obedient and diligent. God gave him particular instructions concerning this building. It must be made of Gopher - wood; Noah, doubtless, knew what sort of wood that was, though now we do not. He must make it three stories high within: and, He must divide it into cabins with partitions, places fitted for the several sorts of creatures, so as to lose no room. Exact dimensions are given him, that he might make it proportionable, and might have room enough in it to answer the intention, and no more. He must pitch it within and without: without, to shed off the rain, and to prevent the water from soaking in; within, to take away the ill smell of the beasts when kept close. He must make a little window towards the top to let in light. He must make a door in the side of it by which to go in and out.
