Seeing Sodom and Gomorrah go up in smoke, then seeing his dear wife turned into a pillar of salt, Lot wasn’t in a frame of mind to enjoy the town of Zoar where he’d gone – instead of to the hill-country – in order *to save face in front of his family.*
So shaken was Lot by what had happened to his wife, that he developed an irrational fear of Zoar. The town seemed to him spooky. Lot therefore decided to leave Zoar. Where now to go? Lot decided on the hill-country where his two daughters had gone.
As he made his way to the hill-country, Lot reflected that if only he’d gone to the hill-country with all his family in the first place, he might have been saved the anguish of seeing his dear wife become a pillar of salt, because she just might not have looked back at Sodom and Gomorrah if she’d gone the route to the hill-country instead of the route to Zoar.
“How could I have been so silly”, Lot kept saying to himself as he trudged alone towards the hill-country.
On arriving in the hill-country, Lot was able to track down his two daughters.
“It’s good to see you, father” they said when they saw him. “Where’s mother?” .
“It’s good to see you girls too” said Lot. “I’ve sad news, though, about your mother. She turned into a pillar of salt.”
“What?!!” said the girls.
“We were walking towards Zoar and were just chatting, like” said Lot. “There was this terrific noise behind us which came from Sodom and Gomorrah as they were being destroyed. Your mother stopped to look back at the smoke as it rose into the sky from the smouldering ruins of Sodom and Gomorrah. Suddenly….poof…..your mother became a pillar of salt. It was a shock let me tell you. I tried talking to this pillar of salt that had been your mother. It didn’t move and it said nothing. There was nothing I could do.”
“Good grief!!” said the girls.
“So listen” said Lot, “I’d like the three of us to live together. Is there anywhere here where we can set up a home”.
“Well, there’s this cave” said the girls “There are no animals living in it right now. It would be a nice secluded place for us to make a home.”
In the the first evening together in the cave, the two girls obtained a container of wine. It was a means to temporarily dissipate their sorrow over what had happened to Lot’s wife, the girls’ mother.
After much wine had been drunk, the elder daughter said in a low voice to her sister, “Our father is old, and there isn’t a man in this country who has taken an interest in us, know what I’m saying? Why don’t we get father really drunk, then we’ll lie with him. In this way we’ll keep our family alive through him.”
“Yes, let’s” said the younger daughter.
The drinking continued, and Lot became senseless. The elder daughter, after motioning her sister to go outside the cave, lay with Lot, who was so drunk that he didn’t know what was happening.
Next day the elder daughter said to her sister, “Last night I lay with father. Tonight I want you to do likewise after we’ve given him lots of wine to drink.”
The younger daughter, now sober, said, “I’m having second thoughts.”
“I know this isn’t quite what we should be doing with father” said the elder daughter, “but remember, only by doing this will we keep our family alive through our father. It is for the Greater Good.”
The following evening went as had the evening before. Much wine was drunk by all three. When Lot was senseless, the elder daughter discreetly left the cave while her sister lay with her father, who, as in the night before, didn’t know what was happening.
Both daughters, accordingly, came to be with child by their father. The elder daughter bore a son whom she called Moab. Moab was to become the ancestor of the Moabite peoples. The younger daughter also bore a son whom she called Ben-ammi. This same Ben-ammi later became the ancestor of the Ammonite peoples.
