Bede : You shall make a window in the ark, and you shall finish it to a cubit from above. A window is commanded to be made in the ark so that, after the rains ceased and the ark rested, Noah might release a bird through it to ascertain whether the waters had ceased, or whether the earth had dried or sprouted, so that he also, having opened it, might see the light of the sky; hence in Hebrew it is aptly translated as having the noon, because windows are usually illuminated more clearly by the midday sun; which also aptly accords with spiritual sacraments. For the window, which illuminated the inhabitants of the ark with the splendor of the midday sun only after the flood had passed, suggests that knowledge of heavenly mysteries which is more fully revealed to the baptized faithful. Moreover, the fact that the top of the ark is said to be finished in a cubit indicates that it had three hundred cubits of length and fifty cubits of width at the bottom; gradually narrowed at the corners, it was collected into the space of one cubit at the top, thus becoming shorter and narrower as it rose higher. And indeed, as far as the necessity of rains and the flood is concerned, no form could have been given to the ark more appropriate than that the downpour of rains should be dispersed from the narrow summit of the roof when, the floodgates of heaven having been opened, the rain fell for such a long time; but this form of the ark also mystically suits the state of the holy Church. For just as the ark was broader in the lower parts, where it is believed to have contained animals; it was narrower in the upper parts, where it contained men and birds until it reached the measure of one cubit at the top; thus the Church has more carnal than spiritual members, more who are inclined like quadrupeds by the whole gaze of their mind to desire earthly things than those who, like birds, seek heavenly things with the wings of virtues; and as the holier each person in it is, the fewer they are found to be, until they reach the Mediator between God and men, who appeared as a man among men, yet is above all, God blessed forever. — Commentary on Genesis (Hexaemeron) Bede : You shall place the door of the ark on the lower side. This door, through which men and all the animals to be saved in the ark entered, signifies the unity of faith, without which no one can enter the Church; for there is one Lord, one faith, one baptism; one God, which is aptly commanded to be placed on the side of the ark, because it clearly designates that door, which was opened in the side of the Crucified Lord Savior by the soldier's lance, from which immediately flowed blood and water: through these sacraments, each of the faithful is received into the communion of the holy Church as into the insides of the ark. Moreover, the door of the ark is commanded to be made not only on the side but also below, so that the humility of either the Lord himself by which he died for us or ours, without which we cannot be saved, is signified. Also, the door of the ark was made below and near the ground, so that men or animals to be saved could enter it, and having entered, immediately ascended to the higher places to their respective seats, because the Lord, appearing in the depths of this mortality, was wounded for our iniquities, so that through the sacraments of his wounds, we being redeemed might be led to the heavenly mansions of virtues in the present and to the heavenly rewards with an invisible ascension. This is also well expressed in Solomon's temple, the door by which it was ascended to the upper parts, concerning which it is thus written: "The entrance of the middle side was on the right side of the house;" which some interpret as stating that the temple had an entrance from the southern part, which is far from the truth. For if it wanted to be understood this way, Scripture could briefly say: "And it had an entrance to the South or to the South." But the temple itself actually had an entrance from the rising of the sun. What is said: "The entrance of the middle side was on the right part of the house," the right part of the house is called the southern part, in whose middle side was the door by which it was ascended to the upper parts, with the entrance beginning from the eastern part of the same side, that is, from the very corner, and gradually proceeding to the upper rooms through the interior of the middle wall; hence it is subsequently added: "And they ascended by winding stairs to the middle chamber, and from the middle to the third." Therefore, because the Lord, when he said to the Jews, "Destroy this temple, and in three days I will raise it up" (John 2:19), was speaking of the temple of his body, the door in the right side of this temple, is it not evident that it is the very door which was opened in his right side after the passion, as we said above, through the opening of which we transition from the present life of the holy Church to the eternal rest of souls in the future life, in the example of those who entered the right side of the temple and ascended to the middle chamber by winding stairs. But even after the most blessed rest of souls, we may ascend to the reception of spiritual bodies, as if from the middle chamber to the third, from which we may rejoice with God in the perpetual immortality of both, that is, the soul and the body. — Commentary on Genesis (Hexaemeron) Bede : You shall make upper rooms and lower rooms in it. Lower rooms denote a triple roof. For "stege" in Greek means "roof"; hence ancient interpreters for this word used "tricamerata." Finally, in the Acts of the Apostles, where a young man, whom Paul the Apostle revived from death, is said to have fallen from the third roof or upper room, in Greek it is written that he fell from the "tristego." But upper rooms and lower rooms, as early translators said, were made two-chambered and three-chambered in the ark, such that in distinct seats they would house animals of various kinds. Beasts, indeed, as it is believable, in the lowest parts; clean animals in the higher parts; humans and birds in the highest. For it is certain that where man sat, there too were the raven and dove, and consequently other birds too, located near the window, which is believed to have been made in the highest parts of the ark. For through this window he sent out the aforementioned birds, to see how the land's face fared; in these roofs as well, various little chambers were made, as stated above, for the distinction of the same animals or birds, so that some might not harm others, the more violent not harming the gentler. It is not in vain that Scripture states upper rooms and lower rooms were made in the ark, or that it was made two-chambered and three-chambered, when it could have said in one word that it was arranged in five upper rooms or roofs; but it said it was two-chambered, to signify that in the Church the circumcised and the uncircumcised, Jews and Greeks, will be saved. And three-chambered to signify the triple yield of the evangelical seed, thirtyfold, sixtyfold, hundredfold; so that in the lowest resides marital chastity, above it widowhood, and above that virginity. Moreover, Origen says that in the lower parts the ark was made two-chambered, so that the lowest region would receive dung, the second would be assigned to storing feed; but in the higher parts three-chambered, so that in the first of these parts would be quarters for beasts, in the second stalls for gentler animals, in the highest the seat for humans. — Commentary on Genesis (Hexaemeron) Jerome : (Verse 16.) Assembling, you shall make an ark, and you shall finish it with a cubit from above. As for the reason why it says, assembling, you shall make an ark, in Hebrew it has, 'you shall make the middle of the ark,' which Symmachus interpreted more clearly, saying 'transparent,' that is, making the ark clear, intending for a window to be understood. — Hebrew Questions on Genesis Augustine of Hippo : WHAT DOES THE SCRIPTURE MEAN ABOUT THE CONSTRUCTION OF THE ARK: AND THE DOOR OF THE ARK YOU SHALL MAKE ON THE SIDE; WITH LOWER, SECOND, AND THIRD STORIES SHALL YOU MAKE IT? — The lower floor was not to receive two and three rooms. Using this distinction, God wanted to make it clear that the entire Ark had to have a lower part. Then, above, a floor, which he calls a second rooms; Higher up finally, another floor, or a third vault. So in the first dwelling, I mean, in the lower part, the Ark had a first vault; In the second dwelling, which was above the first, it was also vaulted; So was she again and a third time in the third dwelling, which rose above the second.
