Genesis 28:18-22

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).

20Then Jacob made a vow (promise), saying, “If God will be with me and will keep me on this journey that I take, and will give me food to eat and clothing to wear,

21and if [He grants that] I return to my father’s house in safety, then the Lord will be my God.

22This stone which I have set up as a pillar (monument, memorial) will be God’s house [a sacred place to me], and of everything that You give me I will give the tenth to You [as an offering to signify my gratitude and dependence on You].”
