B'resheet (Gen) 28:20-22

Ya‘akov took this vow: “If God will be with me and will guard me on this road that I am traveling, giving me bread to eat and clothes to wear, so that I return to my father’s house in peace, then ADONAI will be my God; and this stone, which I have set up as a standing-stone, will be God’s house; and of everything you give me, I will faithfully return one-tenth to you.”
