Biblical vows are solemn promises made to God, often found in the Bible. These vows can involve commitments to serve God, offer sacrifices, or dedicate oneself to a specific purpose. They reflect a deep sense of devotion and accountability, emphasizing the importance of keeping one's word. In the Old Testament, figures like Hannah and Samson made significant vows that shaped their lives and destinies. Vows can also be seen in the context of Nazirite vows, which involve abstaining from certain activities to honor God. Overall, biblical vows highlight the seriousness of commitments made in faith.
