Arcana Coelestia # 2453
2453. Verse 26 And his wife looked back behind him, and she became a pillar of salt.
'His wife looked back behind him' means that truth turned away from good and looked towards matters of doctrine. 'And she became a pillar of salt' means that all good accompanying truth was vastated.
Matthew 24:15-17
15
"When, therefore, you see the abomination of desolation, which was spoken of through Daniel the prophet, standing in the holy place (let the reader understand),
16
then let those who are in Judea flee to the mountains.
17
Let him who is on the housetop not go down to take out things that are in his house.
