Genesis 28:20-22

Then Jacob made a vow, saying, “If God will be with me and watch over me on this journey, and if He will provide me with food to eat and clothes to wear, so that I may return safely to my father’s house, then the Lord will be my God. And this stone I have set up as a pillar will be God’s house, and of all that You give me I will surely give You a tenth.”
