The Sefer אישי התנ״ך / the encyclopaedia of biblical personalities brings the sifri Beracha 34:51 “ A tunnel cave connected Moses grave with the graves of the patriarchs.”
I can’t seem to find this. I have Googled the Sifri Beracha and nothing comes up and I have checked on sefaria as well.
Could it be a misprint? If so what is the actual source?
Wishing everyone a Chag Kosher L’Pesach.
