He was afraid — So far was he from being puffed up. The more we see of God, the more cause we see for holy trembling and blushing before him. Those whom God is pleased to manifest himself to, are laid and kept very low in their own eyes, and see cause to fear even the Lord and his goodness, Hosea 3:5. And said, How dreadful is this place! — That is, the appearance of God in this place is to be thought of, but with a holy awe and reverence; I shall have a respect for this place, and remember it by this token as long as I live. Not that he thought the place itself any nearer the divine visions than any other places; but what he saw there at this time was, as it were, the house of God, the residence of the Divine Majesty, and the gate of heaven, that is, the general rendezvous of the inhabitants of the upper world; as the meetings of a city were in their gates; or, the angels ascending and descending were like travellers passing and repassing through the gates of a city.
