Genesis 28:18-22 NIV
Early the next morning Jacob took the stone he had placed under his head and set it up as a pillar and poured oil on top of it. He called that place Bethel, though the city used to be called Luz.
Then Jacob made a vow, saying, “If God will be with me and will watch over me on this journey I am taking and will give me food to eat and clothes to wear so that I return safely to my father’s household, then the LORD will be my God and this stone that I have set up as a pillar will be God’s house, and of all that you give me I will give you a tenth.”
