Jacob's Vow at Bethel
A vow of allegiance and dependence.
Jacob responds to God's promise with a vow: if God keeps him and brings him home, Jacob will worship the Lord and dedicate a tenth.
Scripture
Genesis 28:20-22
20 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,
21 so that I come again to my father's house in peace, and Yahweh will be my God,
22 then this stone, which I have set up for a pillar, will be God's house. Of all that you will give me I will surely give the tenth to you."
