Parashas Vayeitzei · Passuk 28:17
And he was afraid and said, “How awesome is this place! This is none other than the house of God, and this is the gate of heaven.”
Torah Temimah points to classical sources on the identification of the place with the future Beis HaMikdash (Chullin 91b / Bereshis Rabbah parallel).
TT lemma: מה נורא המקום.
English: Rabbi Elazar said in the name of Rabbi Yosei ben Zimra: This ladder stood in Be’er Sheva and its slope reached opposite the Beis HaMikdash.
Derash on the verse (midrashic / Bavli parallel) — not a formal named middah of the 13. The geographic placement of the ladder links the dream to the Temple site.
The place Yaakov recognized as the house of God and gate of heaven is the future site of the Beis HaMikdash.
