42. If Moses in this passage is speaking of the civil year, then the flood occurred in September or October, an opinion I find Lyra held. It is true that fall and winter are more liable to rains, the signs of the zodiac pointing to humidity. Again, as Moses writes further on, a dove was sent forth in the tenth month and brought back a green olive branch. This fact seems to harmonize with the view that the deluge began in October.
43. But I cannot endorse this argument of the Jews, assuming two beginnings of the year. Why not make four beginnings, since there are four distinct seasons according to the equinoxes and solstices? It is safer to follow the divine order, making April the first month, starting with the new moon which is nearest to vernal equinox. The Jews betray their ignorance in speaking of an autumnal beginning of the year: the autumnal equinox is necessarily the end of the year. Moses so calls it for the reason that all field labors had then ceased and all products had been gathered and brought home.
44. Hence, it is my belief that the flood began in the spring, when all minds were filled with hope of the new year. Such is the death of the wicked that when they shall say, "Peace and safety," they perish. 1 Thes 5, 3. Nor is any inconsistence shown in the fact that the green olive branch is afterward mentioned, for certain trees are evergreen, as the boxwood, fir, pine, cedar, laurel, olive, palm and others.
45. But what does Moses mean by saying that the fountains of the great deep burst, and that the windows of heaven were opened? No such record is found in all pagan literature, although the heathen searched with zeal the mysteries of nature. One discrimination should be made as regards the abysses of the earth, the floodgates or windows of heaven, and the rain. Rain, as we know it, is a common phenomenon, while that of bursting floodgates and abysses is both unfamiliar and amazing.
46. Almost all interpreters are silent on this point. We know from Holy Writ that God, by his Word, established a dwelling-place for man and other living beings on dry land, above the water, contrary to nature; for it is opposed to natural law that the earth, being placed in water, should rise up out of it. If you cast a clod into the water, it sinks at once. But the dry land stands up out of the water by virtue of the Word, which has set bounds for the sea, as Solomon (Prov 8, 27) and Job (ch 38, 11) declare. Unless the water were restrained by the power of the Word, with a bound, as it were, they would overflow and lay waste everything. Thus is our life guarded every single moment, and wonderfully preserved by the Word. We have an illustration in partial deluges, when at times entire states or regions are flooded, proving that we should daily suffer such unpleasant things if God did not take care of us.
