The concept of a "secret oath" is not explicitly detailed in the Bible, but the idea of oaths, vows, and secretive agreements is present throughout the Scriptures. Oaths in biblical times were solemn promises made before God, often invoking His name as a witness to the truthfulness and binding nature of the commitment. The Bible provides guidance on the seriousness of making oaths and the importance of fulfilling them.

Old Testament Context

In the Old Testament, oaths were a common practice and were considered binding. The Law of Moses provided specific instructions regarding vows and oaths. In Numbers 30:2 , it is stated, "When a man makes a vow to the LORD or swears an oath to bind himself by a pledge, he must not break his word; he must do everything he has promised." This underscores the gravity of making an oath and the expectation of its fulfillment.

The account of Jephthah in Judges 11 illustrates the potential consequences of rash vows. Jephthah made a vow to the Lord, saying, "If You give the Ammonites into my hands, then whatever comes out of the door of my house to greet me on my return in triumph from the Ammonites will belong to the LORD, and I will offer it up as a burnt offering" (Judges 11:30-31). His vow, made in haste, led to tragic results, highlighting the need for careful consideration before making such commitments.

New Testament Teachings

In the New Testament, Jesus addresses the issue of oaths in the Sermon on the Mount. He teaches, "Again, you have heard that it was said to the ancients, 'Do not break your oath, but fulfill your vows to the Lord.' But I tell you not to swear at all: either by heaven, for it is God’s throne; or by the earth, for it is His footstool; or by Jerusalem, for it is the city of the great King" (Matthew 5:33-35). Jesus emphasizes the importance of honesty and integrity, suggesting that one's word should be sufficient without the need for oaths.

James, in his epistle, reiterates this teaching: "Above all, my brothers, do not swear, not by heaven or earth or by any other oath. Simply let your 'Yes' be 'Yes,' and your 'No,' 'No,' so that you will not fall under judgment" (James 5:12). This instruction aligns with the call for Christians to live truthfully and transparently, avoiding the need for secretive or binding oaths.

Secretive Agreements and Deception

While the Bible does not specifically mention "secret oaths," it does address the issue of secretive agreements and deception. In the account of Jacob and Laban, we see the use of deception in agreements. Laban deceives Jacob by giving him Leah instead of Rachel after Jacob had worked seven years for Rachel's hand in marriage (Genesis 29:25). This narrative highlights the complications and moral issues that arise from secretive or deceptive dealings.

The account of Ananias and Sapphira in Acts 5 serves as a New Testament example of the dangers of deceit. They secretly conspired to lie about the proceeds from the sale of their property, resulting in severe consequences. This account underscores the importance of honesty and the perils of secretive, dishonest agreements within the Christian community.

Conclusion

The Bible consistently teaches the importance of truthfulness, integrity, and the careful consideration of one's words and commitments. While the concept of a "secret oath" is not directly addressed, the principles surrounding oaths, vows, and secretive agreements provide valuable guidance for believers seeking to live in accordance with God's will.
