Genesis 28:20-22

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.”
