Genesis 28:20 - 28:22
20 Then Jacob made a vow, saying, “If God will be with me and will keep me on this journey on which I am going, and will give me food to eat and garments to wear, 21 and I return to my father’s house in peace, then Yahweh will be my God. 22 Now this stone, which I have set up as a pillar, will be God’s house, and of all that You give me I will surely give a tenth to You.”
