"Tuesday forenoon, November 4, was the time set for the departure from Salamanca. In the morning Elders A. T. Robinson and W. C. White called to see what Mrs. White had decided to do. Then she told them of her experience of the evening before, and of her peace and joy through the night. She said that during the night she had had no inclination to sleep; for her heart was so filled with joy and gladness. Many times she had repeated the words of Jacob: “Surely the Lord is in this place; and I knew it not.” “This is none other but the house of God, and this is the gate of heaven.” Genesis 28:16, 17 . LS 310.5"
"And Jacob awaked out of his sleep, and he said, Surely the Lord is in this place; and I knew it not."
EGW directly quotes Genesis 28:16, indicating a clear and intentional allusion.
