Genesis 28:15-17

And, behold, I am with thee, and will keep thee in all places whither thou goest, and will bring thee again into this land; for I will not leave thee, until I have done that which I have spoken to thee of. And Jacob awaked out of his sleep, and he said, Surely the LORD is in this place; and I knew it not. And he was afraid, and said, How dreadful is this place! this is none other but the house of God, and this is the gate of heaven.
