Midrash sur Job 36:16

[Variantly: "until Tzoar": He showed him the wife of Lot, (who had been turned into a pillar of salt), it being written here "until Tzoar," and elsewhere (Bereshith 19:23) "and Lot came to Tzoar" [followed by (Ibid. 26) "and she was turned into a pillar of salt"]) Variantly: "until Tzoar": He showed him Gehinnom near her, which is narrow above and wide below, as it is written (Iyyov 36:16) "And He has also led you from a mouth narrow-wide, with no constriction beneath it."] Variantly: "until Tzoar": He showed him the oppressors of Israel, like the tax-gougers, who lived with the exiles and were destined to go lost with them.
