"How awesome is this place." Our Sages said: See, the Holy Temple is built and destroyed, and then rebuilt. Built, as it is stated, "how awesome is this place." And destroyed, as it is stated, "none other." And rebuilt, as it is stated, "the abode of God etc." Another interpretation: "How awesome is this place." It is appropriate to be in awe of this place (or God). "This is the gateway to heaven." It teaches that Jacob, our Father, got up and early and saw the Shechina above his head and was afraid, as there were angels going up and down upon him.
