I think another way to look at in both examples. The Genesis and what another poster offered "the same as Judges 19."
I would offer in that parable God was confirming unbelief in their hearts. Therefore sending them a strong delusion to believe the lie.
it was like when the faithless Jews that gathered themselves together as their own fleshly desires because of their jealousy of the surrounding Pagan nations. As foundation they wanted Kings ruling it over their faithlessness .They refused to walk by faith. No desire of serving a King not seen. Called "no faith" in the bible. No understanding of God.
God sent them a strong delusion to keep on believing the lie
Signs are designed for those who will not believe.. . Prophecy, the word of God. The concubine in that parable is used to represent the divorced bride as the other non born again Israel or also called the strange woman.. or harlot. . Cut her up into twelve divisions (sects or denominations ) to show there was no agreement with God, no unity amongst the brethren. Sent them a strong delusion as a sign of their rebellion.
The Levite the mediator as a priest.
Behold, here is my daughter a maiden, and his concubine; them I will bring out now, and humble ye them, and do with them what seemeth good unto you: but unto this man do not so vile a thing. But the men would not "hearken to him:" so the man took his concubine, and brought her forth unto them; and they knew her, and abused her all the night until the morning: and when the day began to spring, they let her go. Then came the woman in the dawning of the day, and fell down at the door of the man's house where her lord was, till it was light. And her lord rose up in the morning, and opened the doors of the house, and went out to go his way: and, behold, the woman his concubine was fallen down at the door of the house, and her hands were upon the threshold. And he said unto her, Up, and let us be going. But none answered. Then the man took her up upon an ass, and the man rose up, and gat him unto his place. And when he was come into his house, he took a knife, and laid hold on his concubine, and divided her, together with her bones, into twelve pieces, and sent her into all the coasts of Israel. Judges 19: 24-29
Twelve to represent the whole or unity. Again divided as a sign to represent no unity
The parable in Genesis is similar in that the wife was turned in salt. A sign of the judgment of death against those who rebel against prophecy God's word .like the woman in Judges that fell dead at the door step not entering into the house And the daughters were used to represent by dividing into two gentiles nations. Moab the Moabites and Amon the Ammonites coming from them again to represent unbelievers no faith that comes from hearing God.
In that way we compare the spiritual unseen understanding of one parable to another. That would seem to fit the prescription for rightly dividing that I will offer below.
Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.1 Corinthians 2:13
