Genesis 28:16-18
16
Jacob awakened out of his sleep, and he said, "Surely Yahweh is in this place, and I didn't know it."
17
He was afraid, and said, "How dreadful is this place! This is none other than God's house, and this is the gate of heaven."
18
Jacob rose up early in the morning, and took the stone that he had put under his head, and set it up for a pillar, and poured oil on its top.
