I heard in a shiur about manuscripts of the Ben Ish Chai found by American troops among 2,700 seforim and tens of thousands of Jewish documents in a flooded basement of Iraq’s intelligence headquarters after Saddam Hussein’s downfall in 2003 (see here) .
In particular he wrote about the connection between the loshon hora of Miriam in Behaalotecha and the sin of the spies in Shelach. The normal punishment for loshon hora is leprosy and that was not the punishment of the spies. The Ben Ish Chai suggests that the common factor is not loshon hora but lack of respect for Moshe.
Has anyone seen either the text of this Ben Ish Chai or a write-up of the dvar Torah please?
