Genesis 28:16-19

16Then Jacob awoke from his sleep and he said, “Without any doubt the Lord is in this place, and I did not realize it.”

17So he was afraid and said, “How fearful and awesome is this place! This is none other than the house of God, and this is the gateway to heaven.”

18So Jacob got up early in the morning, and took the stone he had put under his head and he set it up as a pillar [that is, a monument to the vision in his dream], and he poured [olive] oil on the top of it [to consecrate it].

19He named that place Bethel (the house of God); the previous name of that city was Luz (Almond Tree).
