53. Moses' use here of the word "windows" signifies the literal opening of heaven. With rain as we know it, the water appears to fall by drops from the pores of the rain-clouds, but at the time of the flood it came down with great force, not through pores, but through windows, like water poured from a vessel with one movement, or as when water-skins burst in the middle. Moses uses this figure of speech for the sake of effect, so that those occurrences are brought to our vision.
54. A volume of water, therefore, swept over the earth, from the sky as well as from the innermost parts of the earth, until at last the whole earth was covered with water, and the fertile soil, or the entire face of the earth was destroyed by the briny flood. A like instance occurs nowhere in any book. The Holy Scriptures alone teach us that these things were visited upon the world sinning in imagined security, and that to this day the waters suspended in the clouds are restrained only by the kindness of God. Otherwise they would descend in vast volume, as in the flood, according to the law of their nature.
Vs. 13-16. In the selfsame day entered Noah, and Shem, and Ham, and Japheth, the sons of Noah, and Noah's wife, and three wives of his sons with them, into the ark; they, and every beast after its kind, and all the cattle after their kind, and every creeping thing that creepeth upon the earth after its kind, and every bird after its kind, every bird of every sort. And, they went in unto Noah and the ark, two and two of all flesh wherein is the breath of life. And they that went in, went in male and female of all flesh, as God commanded him.
55. Here Moses begins to be remarkably verbose. His wordiness hurts tender ears when he so often and apparently without any use repeats the same things. It is not sufficient to say "all birds," but he names three kinds of birds. Of these, the term zippor is usually said to mean "a sparrow," but this passage shows clearly that it is a generic term, doubtless so called from the sound, zi, zi. He also names three kinds of beasts. Also, when speaking of the flood itself, he is very wordy, saying that the waters prevailed, that they increased, that they flooded and covered the face of the earth. Finally, when he tells of the effect of this flood, he makes similar repetition: "All flesh expired, died, was destroyed," etc.
56. But I said above ([§37]) that Moses repeats these things contrary to his style, in order to force the reader to pause and more diligently learn and meditate upon this great event. We cannot fully comprehend the wrath which destroys, not man alone, but all his possessions. Moses wishes to arouse hardened and heedless sinners by such a consideration of God's wrath.
57. Hence, these words are not idle, as a shallow and unspiritual reader might judge. They rather challenge us to fear God, and call attention to the present so that, sobered by the thought of such wrath, we may make an earnest beginning in the fear of God, and cease from sin. For not without many tears does Moses appear to have written this account! So utterly is he with eyes and mind absorbed in this horrible spectacle of wrath that he cannot but repeat the same statements again and again. Doubtless he does this with the purpose to thrust such darts of divine fear, so to speak, into the souls of pious readers.
