דברים, פרק ו׳, פסוק י״ג

The relationship between a person and God develops in progressive stages, moving from the internal emotions of the heart to physical actions, and finally culminating in the most binding verbal expressions. Following the earlier directive to love God, the focus shifts to the interconnected duties of reverence, service, and the taking of oaths.

Reverence, or awe, is meant to complement the trait of love. While love draws a person close to God, awe serves to deter an individual from sin and its resulting consequences [רמב״ן, טור, רבנו בחיי]. In truth, genuine awe blossoms directly from love itself. When a person loves God and contemplates His immense greatness, a natural reverence awakens, preventing them from doing anything that would displease their Creator [שפתי כהן, ביאור יש״ר]. This reverence is practically expressed by carefully avoiding the violation of negative commandments [אבן עזרא], and by maintaining the absolute recognition that all success and abundance depend solely upon God [מלבי״ם]. Even when blessed with prosperity, a person must remember that everything is granted simply as a means to serve Him [בכור שור]. Furthermore, this duty of reverence extends outward, encompassing an obligation to show respect and awe toward Torah scholars [הכתב והקבלה, תורה תמימה].

Once reverence is established in the heart, it transitions into practical service. This means submitting to and executing God's will with the dedication of a servant, rooted in the understanding that the Israelites were redeemed from physical slavery specifically to become servants of God [רמב״ן, טור, רלב״ג, מלבי״ם, ביאור יש״ר]. This dedication is fulfilled through the observance of positive commandments [אבן עזרא]. Commentators identify three primary avenues for this service: the sacrificial rites in the Temple, the study and contemplation of Torah, and prayer, through which a person acknowledges complete dependence on God for all needs [רמב״ן, טור, רלב״ג, ביאור יש״ר]. At its highest level, this service encompasses a person's entire existence. Even basic physical needs, such as eating and sleeping, are done for the sake of heaven, serving to gather strength to continue fulfilling God's will [רמב״ן].

The final stage, the taking of oaths, presents a profound discussion among commentators. One perspective views this as a positive commandment: if a person is required to swear in court to verify a matter, they must swear specifically by God's name, as this expresses honor, greatness, and an acknowledgment of His providence [מזרחי ומיני תרגומא בדעת הרמב״ם]. However, the primary approach among commentators is that this is not an encouragement to take oaths, but rather a warning and a limitation. While oaths are generally discouraged, if circumstances force a person to make a covenant or verify a claim, they must swear exclusively by God's name, rather than by other deities or forces of nature [רמב״ן, טור, אבן עזרא, רבנו בחיי, בכור שור, ביאור יש״ר, תורה תמימה].

Crucially, the permission to swear is intimately tied to the preceding stages of reverence and service. Only someone who has genuinely acquired awe of God will treat an oath with the necessary gravity, ensuring they never use His name in vain or falsely [רש״י, רמב״ן, רבנו בחיי, מזרחי, רא״ש, גור אריה, משכיל לדוד, דברי דוד, רש״ר הירש]. There are also situations where an oath serves as a positive tool, such as when a person swears in order to motivate themselves to perform a commandment or to overcome a negative inclination [צאינה וראינה, מיני תרגומא]. From a purely emotional standpoint, swearing by God's name can also stem from immense love and a deep spiritual connection. Just as someone might swear by the life of a beloved child out of deep affection [שפתי כהן], invoking God's name in an oath demonstrates to the world that the individual is deeply bound and devoted to their Creator [חזקוני, רש״ר הירש].
