Genesis 28:20-22 NIV

Then Jacob made a vow, saying, “If God will be with me and will watch over me on this journey I am taking and will give me food to eat and clothes to wear
so that I return safely to my father’s household, then the LORD will be my God
and this stone that I have set up as a pillar will be God’s house, and of all that you give me I will give you a tenth.”
