The story, as told in Genesis 19:31, has Lot’s daughters deeply concerned. "Our father is old," they say, "and there is no man on earth to consort with us in the way of the world."

Why such a dire conclusion? Well, according to Bereshit Rabbah 51, they believed the entire world had been destroyed, just like in the time of the Flood. They thought they were the only people left! A pretty understandable mistake, given the circumstances.

So, what do they do? They hatch a plan. "Let us give our father wine to drink, and we will lie with him, and we will give life to offspring from our father" (Genesis 19:32).

Now, this is where it gets…complicated. Rabbi Tanhuma, quoting Rabbi Shmuel, points out a key detail: the verse doesn't say "we will give life to a child from our father," but "we will give life to offspring from our father." The distinction, according to this interpretation, is crucial. It hints at a future lineage, "that offspring that will come from another place." And what is that other place? The messianic king! The Messiah, a descendant of David, would be a distant relative of Lot, through Moab and Ruth.

The plan unfolds: they get their father drunk. Genesis 19:33 tells us, "They gave their father wine to drink that night. The elder came and lay with her father and he was not aware when she lay and when she arose.” But there’s a tiny, yet telling, detail in the Hebrew text. There's a dot over the vav in the word uvkuma (and when she arose). The Sages of the Midrash see this as an intimation. According to this subtle hint, he was unaware when she lay down, but became aware when she arose.

The next day, the elder daughter proposes they repeat the act. Where did they even get the wine in that desolate cave, you might ask? Rabbi Yehuda bar Simon offers a fascinating explanation: the people of Sodom were overflowing with wine and hid it away in caves. But even more strikingly, he says that something resembling a sample of the World to Come was provided for them. It arrived miraculously, so that Lot’s daughters could intoxicate him and have children, from whom David would descend! He even quotes Joel 4:18: "It will be on that day, that the mountains will drip with juice," connecting this event to Messianic times.

So, what are we to make of this story? It's uncomfortable, to say the least. But within its discomfort lies a profound message. Even from morally questionable actions, even from the most unlikely of circumstances, redemption can emerge. The line of David, the line of the Messiah, springs from this very human, very flawed, and frankly, very strange series of events. It’s a reminder that even in the darkest corners, hope, and the potential for greatness, can still be found. Perhaps that's the most important lesson this unusual story teaches us.
