"Keeping Vows in the Bible (except when repentance required for a vow to sin, or a sinful vow)
"The Bible emphasizes the importance of keeping one’s vows, even if it is difficult or costly. This principle is highlighted in
Psalm 15:4, which describes a righteous person as one “who keeps an oath even when it hurts, and does not change their mind.” This verse underscores the value of integrity and the importance of one’s word, suggesting that a person’s commitment to their promises should be steadfast, regardless of the personal cost.
Additionally, Jesus’ teachings in Matthew 5 support this principle by advising against the use of elaborate expressions or oaths to lend credibility to one’s words. Instead, Jesus emphasizes the importance of one’s word being reliable, advocating for simplicity in communication and commitment.
The Old Testament also provides examples of this principle, such as the story of Amaziah, the king of Judah, who, despite facing financial strain, remained committed to his promises and obligations."
