Genesis 28:20-22

²⁰Then Jacob made a vow, saying, “If God will be with me, and keep me in this way that I am going, and give me bread to eat and clothing to put on, ²¹so that I come back to my father’s house in peace, then the Lord shall be my God. ²²And this stone which I have set as a pillar shall be God’s house, and of all that You give me I will surely give a tenth to You.”
