Genesis 28:18-22
So early in the morning Jacob took the stone that he had put under his head and set it up for a pillar and poured oil on the top of it.He called the name of that place Bethel, but the name of the city was Luz at the first.Then Jacob made a vow, saying,“ If God will be with me and will keep me in this way that I go, and will give me bread to eat and clothing to wear,so that I come again to my father’s house in peace, then the Lord shall be my God,and this stone, which I have set up for a pillar, shall be God’s house. And of all that you give me I will give a full tenth to you.”
