“Shaken, he said, “How awesome is this place! This is none other than the abode of Hashem, and that is the gateway to heaven” GENESIS 28:17 (The Israel Bible™)
According to Rashi, these words refer to the Temple Mount in Yerushalayim. He explains that the foot of the ladder in Yaakov’s dream was in Be’er Sheva, and its head was in Beit El. Therefore the middle of the ladder hung over Mount Moriah and the intensity of the encounter with Hashem occurred in that spot. When Yaakov awakens, he realizes that he has seen no ordinary place, but “the abode of Hashem,” the most intimate spot for prayers to ascend heavenward and the site where the Beit Hamikdash would later stand. The Beit Hamikdash is referred to here as ‘abode’ or ‘house’ because in the Temple, Hashem’s revealed presence – the shechina (שכינה) – dwells with His people, just as a husband dwells intimately with his wife in their home.
