Genesis 28:20-22

Then Jacob made a vow, saying, “If God will be with me, and will keep me in this way that I go, and will give me bread to eat and clothing to wear, so that I come again to my father's house in peace, then the LORD shall be my God, and this stone, which I have set up for a pillar, shall be God's house; and of all that you give me I will surely give one tenth to you.”
