In the Bible, Jacob made several vows to God. One of the most well-known vows is found in Genesis 28:20-22, where Jacob promises to give a tenth of all he has to God and to worship Him faithfully. Another vow is found in Genesis 31:13, where Jacob promises to serve God and to return to his homeland in peace. Additionally, Jacob makes a vow in Genesis 35:1-3 to build an altar to God and to worship Him alone.
