Genesis 28:20-22

And Jacob vowed 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 put on so that I come again to my father’s house in peace, then shall the LORD be my God; and this stone, which I have set for a pillar, shall be God’s house; and of all that thou shalt give me I will surely give the tenth part unto thee.
