254. As to the door, it is certain that it was about thirteen or fourteen cubits from the earth. The ark, when it floated, sank about ten feet into the water with its great weight of animals of every kind and provender for more than a year. This may suffice as a crude conception of the ark; for, besides height and length, Moses merely indicates that it had three partitions, a door and a window.
255. We will dismiss innumerable other questions such as: What kind of air was used in the ark? for such a stupendous mass of water, particularly falling water, must have produced a violent and pestilential stench; whence did they draw their drinking-water? for water cannot be preserved a whole year, hence mariners often call at ports in their vicinity for the purpose of drawing water; again, how could the bilge-water with its obnoxious odor be drawn up?
256. Such questions and other subordinate points related to the experience of the mariner we may pass by. Otherwise there will be no end of questions. We will be content with the simple supposition that the lower part probably served the purpose of securing the bears, lions, tigers and other savage animals; the middle part, that of housing the gentle and tractable animals, together with the provender, which cannot be kept in a place devoid of all air-currents; the upper that of accommodating human beings themselves, together with the domestic animals and the birds. This should be enough for us.
V. 17. And I, behold, I do bring the flood of waters upon the earth, to destroy all flesh, wherein is the breath of life, from under heaven; everything that is in the earth shall die.
257. Above God has threatened in general the human race with destruction. Here he points out the method; namely, that he intends to destroy everything by a new disaster, a flood. Such a punishment the world hitherto had not known. The customary punishments, as we see from the prophets, are pestilence, famine, the sword and fierce beasts. Men and beasts perish of pestilence. The earth is laid waste by war, for it is deprived of those who till it. The sufferings of famine, though they seem to be less cruel, are by far the most terrible. With the fourth class of penalties, our regions have almost no experience at all. Although these are severally sufficient for the chastisement of the human race, the Lord desired to employ a novel kind of punishment against the primeval world, through which all flesh having the breath of life was to perish.
258. Because this punishment was unheard of in former ages, the wicked were slower to believe it. They reasoned thus: If God is at all angry, can he not correct the disobedient by the sword, by pestilence? A flood would destroy also the other creatures which are without sin; surely God will not plan anything like this for the world.
259. But in order to remove such unbelief from the mind of Noah and the righteous, he repeats with stress the pronoun, "And I, behold, I do bring." Afterward he clearly adds that he will destroy all flesh that is under heaven and in the earth; for he excludes here the fishes whose realm is widened by the waters. This passage tends to show the magnitude of the wrath of God, through which men lose, not only body and life, but also universal dominion over the earth.
