The crowd of sinners tried to take the entrance to the ark by storm, but the wild beasts keeping watch around the ark set upon them, and many were slain, while the rest escaped, only to meet death in the waters of the flood.[25] The water alone could not have made an end of them, for they were giants in stature and strength. When Noah threatened them with the scourge of God, they would make reply: "If the waters of the flood come from above, they will never reach up to our necks; and if they come from below, the soles of our feet are large enough to dam up the springs." But God bade each drop pass through Gehenna before it fell to earth, and the hot rain scalded the skin of the sinners. The punishment that overtook them was befitting their crime. As their sensual desires had made them hot, and inflamed them to immoral excesses, so they were chastised by means of heated water.[26] Not even in the hour of the death struggle could the sinners suppress their vile instincts. When the water began to stream up out of the springs, they threw their little children into them, to choke the flood.[27] It was by the grace of God, not on account of his merits, that Noah found shelter in the ark before the overwhelming force of the waters.[28] Although he was better than his contemporaries, he was yet not worthy of having wonders done for his sake. He had so little faith that he did not enter the ark until the waters had risen to his knees. With him his pious wife Naamah, the daughter of Enosh, escaped the peril, and his three sons, and the wives of his three sons. Noah had not married until he was four hundred and ninety-eight years old. Then the Lord had bidden him to take a wife unto himself. He had not desired to bring children into the world, seeing that they would all have to perish in the flood, and he had only three sons, born unto him shortly before the deluge came.[30] God had given him so small a number of offspring that he might be spared the necessity of building the ark on an overlarge scale in case they turned out to be pious. And if not, if they, too, were depraved like the rest of their generation, sorrow over their destruction would but be increased in proportion to their number.[31] As Noah and his family were the only ones not to have a share in the corruptness of the age, so the animals received into the ark were such as had led a natural life. For the animals of the time were as immoral as the men: the dog united with the wolf, the cock with the pea-fowl, and many others paid no heed to sexual purity. Those that were saved were such as had kept themselves untainted.[32] Before the flood the number of unclean animals had been greater than the number of the clean. Afterward the ratio was reversed, because while seven pairs of clean animals were preserved in the ark, but two pairs of the unclean were preserved.[33]
