Genesis 19:31

That the oldest furtively comes in for but one night, and puts her sister in her stead, the next night, and that they, being pregnant, not think to return to the embrace of their father; from that we decide in the second place, that they have had no other goal but to become mother. But I do not approve of what some conjecture, who say that they were mislead by a great error, thinking that the whole world had perished together with Sodom. For, they had just dwelt in Zoar, also there were sweet regions before their eyes, which were surely not without inhabitants, and also they had learned from their father that a special punishment was inflicted upon the Sodomites and the other neighbors. They also were not ignorant of the family whence their father came, and what kind of uncle he had followed out of his fatherland. So, what must we think? That, because they were assured that families are maintained by children, it was hard for them and it was a continual cause of grief, that they were without children. Also the emptiness, when their father would be dead, could seem to be unbearable for them, because they saw that they then would be lonely, and without any help. So, hence their impudent desire, and that absurd urgency to seek this unchaste intercourse, as they were afraid of a lonely life, which was liable to many concerns. Also I doubt not, that Moses not narrates what they have used as a pretext, but what they have said in a sincere feeling of their hearts. So, they wanted to bring forth seed, like the custom of all the nations. They adduce the example of the entire world, because they would deem it unfair when their state would be worse then that of the others. Everywhere, they say, the young women are praised, who conceive children, and thus build their families; why must we then be condemned to be always childless? In the mean time, they well know that they commit a great sin. For, why make they their father drunken? Is it not, because they guess, that he cannot be made willing? When he has had an aversion to unchastity, the daughters must necessarily have had the same notion in their consciences. So, in no wise they are to be excused, that they lend themselves to a scandalous intercourse, which all the nation abhor by nature. While the people, with normal crimes, are forced to admit their crimes; how will they plead themselves free with important crimes, as if no fear for God’s judgement prickled them? Therefore, with suppression of the conscience, Lot’s daughters devote themselves to that crime. The reason to mislead their father was no other then this, that they knew the disgrace, which they themselves necessarily had to condemn, because they knew that it was against the order of the nature. From this appears, whereto the people come when they follow their own will; for nothing can be so absurd or bestial, that we not decay to that, when we give free rein to our flesh. Let this, therefore, be the beginning of al our desires, to examine what the Lord allows, in order that it comes not in our mind to ask something, what according His Word is free to us.

There is not a man in the earth. They mean not that all the nations are destroyed, as many explainers drivel, but because they are by fear driven in the cave, leading a lonely life, they complain, that they are cut off from any hope of marriage. And yes, being secluded from the rest of the nations, they lived as if they were sent away to some separated world. Might one object that they could ask husbands of their father, then I answer, that it absolutely not a miracle, that they, beaten down through fear, could not seek another medicine, than what was at hand. For, they thought that they on that solitary mountain, locked up in the den of a rock, had no more the least connection with the human race. It could be (as I have reminded before) that some slaves dwelt with them. This is even probable, for otherwise it was difficult to have wine in the cave, when this was not taken with them on a wagon with the other foods. Yet they say that there were no husbands for them, because they have an aversion to a marriage with slaves.

Further I mean, that the name earth in the first member, is put for region or area, as if they said: This region has no more men left, who could marry us after the custom of the entire world. For there is here a tacit contrast between the whole earth and a certain part thereof. But this is their first crime, that they, in a zeal to propagate the human race, violate the holy law of nature. Next, it is wrong and wicked, that they not flee to the Creator of the world Himself, to cure them from that desolation, about which they were worried. Thirdly, they show their negligence when they aim their hearts only on the earthly life, and not worry about the heavenly life. Though I dare not to give security concerning the time, which has elapsed between the destruction of Sodom, and the unchaste intercourse of Lot with his daughters, yet, it is probable that they, as soon as they had come in the cave, in aversion to the solitude, have made up this scandalous and execrable plan. It could not take a long time, that Lot lived in the cave, or there came lack of food and drink. And like a sudden fear had carried away their father, like a storm, likewise the daughters could not restrain themselves, even for some days. Without calling upon God, or asking their father for advice, they are carried away through a bestial instinct. Herein we see how soon the deliverance and the punishment of the Sodomites has left their memory, although both had always to be kept in their heart. Oh, that this vice also among us were not so great; but we show too clearly in both ways our ingratitude.
