Genesis 28:20-22
Genesis 28:20-22 NET
Then Jacob made a vow, saying, “If God is with me and protects me on this journey I am taking and gives me food to eat and clothing to wear, and I return safely to my father’s home, then the LORD will become my God. Then this stone that I have set up as a sacred stone will be the house of God, and I will surely give you back a tenth of everything you give me.”
