Genesis 28:20-22

Then Jacob made a vow, saying, “If God will be with me and will keep me on this journey that I take, and will 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. 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.”
