And Jacob awaked out of his sleep, and he said, Surely the LORD is in this place; and I knew it not.

Wesley's Notes

28:16 Surely the Lord is in this place, and I knew it not - God's manifestations of himself to his people carry their own evidence along with them. God can give undeniable demonstrations of his presence, such as give abundant satisfaction to the souls of the faithful, that God is with them of a truth; satisfaction not communicable to others, but convincing to themselves. We sometimes meet with God there, where we little thought of meeting with him. He is there where we did not think he had been, is found there where we asked not for him.

Jamieson-Fausset-Brown Bible Commentary

16. Jacob awaked out of his sleep-His language and his conduct were alike that of a man whose mind was pervaded by sentiments of solemn awe, of fervent piety, and lively gratitude (Jer 31:36).

Matthew Henry's Concise Commentary

28:16-19 God manifested himself and his favour, to Jacob, when he was asleep. The Spirit, like the wind, blows when and where it listeth, and God's grace, like the dew, tarrieth not for the sons of men. Jacob sought to improve the visit God had made him. Wherever we are, in the city or in the desert, in the house or in the field, in the shop or in the street, we may keep up our intercourse with Heaven, if it is not our own fault. But the more we see of God, the more cause we see for holy trembling before him.
