"If a man makes a vow to God, or makes an oath to obligate himself, he must not break his word." However, a Sage can annul his word. If a woman makes a vow, a Sage, her father, or her husband can annul it.
In the relationship between the Cosmic Man and Cosmic Woman, the Man represents Wisdom, and the Woman – Understanding. Thus, any vow or oath is expressed through Understanding, on the condition that it agrees with Wisdom. If it does not, the Sage can annul it.
The seven breaths that emanate from the mouth of the Cosmic Man turn into an all-encompassing light between him and the Cosmic Woman. These are the seven breaths that are mentioned by King Solomon, and they are the secret meaning of an oath, “shevuah” - seven. Thus there is a mitzvah to swear in the name of God.
One who swears falsely takes himself away from the seven breaths of holiness, and as if clothes the Truth in the seven garments belonging to Forces of Evil, about which King Solomon said, “That, too, is vanity (breath) and evil of spirit.”
