'Oil' in the Bible

So 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].

Jacob set up a pillar (memorial, monument) in the place where he had talked with God, a pillar of stone, and he poured a drink offering [of wine] on it; he also poured oil on it [to declare it sacred for God’s purpose].
