Genesis 28:20-22

²⁰Then Jacob made this vow: “If God will indeed be with me and protect me on this journey, and if he will provide me with food and clothing, ²¹and if I return safely to my father’s home, then the Lord will certainly be my God. ²²And this memorial pillar I have set up will become a place for worshiping God, and I will present to God a tenth of everything he gives me.”
