Genesis 28:18-22

So Jacob got up early in the morning, and took the stone that he had placed as a support for his head, and set it up as a memorial stone, and poured oil on its top.

Then he named that place Bethel; but previously the name of the city had been Luz.

Jacob also made a vow, saying, “If God will be with me and will keep me on this journey that I take, and give me food to eat and garments to wear,

and I return to my father’s house in safety, then the Lord will be my God.

And this stone, which I have set up as a memorial stone, will be God’s house, and of everything that You give me I will assuredly give a tenth to You.”
