Gen 28:18-22

18So Jacob rose early in the morning, and he 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.19He called that place Bethel; but the name of the city was Luz at the first.20Then 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,21so that I come again to my father's house in peace, then the Lord shall be my God,22and this stone, which I have set up for a pillar, shall be God's house; and of all that you give me I will surely give one tenth to you.”
