דברים, פרק י״ז, פסוק י״ט

A monarch's power is vast, and the temptation to rule absolutely is ever-present. To ensure a leader remains grounded, his relationship with divine law cannot be limited to casual reading; it must be the very foundation that shapes his character, restricts his authority, and directs his governance.

The requirement to keep the law close goes far beyond carrying a physical scroll. The essence of this duty is that the teachings and concepts of the Torah must be deeply engraved upon the king's heart [הכתב והקבלה, מלבי״ם]. In a profound sense, the divine law itself miraculously accompanies him on his journey [רמב״ן]. Some explain that the king possesses a personal scroll complete with comprehensive explanations to guide him [ביאור יש״ר].

This presence must be constant. The scroll travels with the king through all his royal duties—whether he is leading an army into battle, sitting in judgment over the government, or simply sitting down to eat. The only exceptions are places unfitting for sacred study, such as a bathhouse or a cemetery [תורה תמימה, אדרת אליהו, מלבי״ם]. His obligation to read throughout his life is taken literally, demanding continuous study during every available moment [העמק דבר, שפתי חכמים, רלב״ג]. This duty specifically includes the nighttime hours as well [תורה תמימה, מלבי״ם, צפנת פענח]. A king carries a heavier burden of study than an ordinary person because his mind requires constant immersion in divine wisdom to lead properly [העמק דבר].

The ultimate goal of this relentless study unfolds in a gradual, transformative process. The primary approach among commentators is that learning acts as the first step in a chain reaction: study brings a person to awe, awe leads to the observance of the commandments, and observance culminates in concrete action [תורה תמימה, אדרת אליהו, מלבי״ם]. Deep study exposes the king to God's greatness and providence, instilling a profound reverence for God, who is constantly watching him [ספורנו, מלבי״ם]. This reverence is especially crucial for a monarch. Sages and prophets help cultivate this awe by teaching him the deeper secrets of leadership appropriate for his high station [ביאור יש״ר].

The responsibility to uphold the teachings and statutes of the law contains multiple layers of meaning. One perspective suggests that the teachings refer to the Written Law, while the statutes represent the Oral Law and its legal derivations [העמק דבר]. Another approach views the teachings as the historical and educational lessons that shape the destiny of the nation. In contrast, the statutes are the absolute moral norms that limit the king's power, serving as a constant reminder that he is subservient to God and that his subjects are his equals [רש״ר הירש]. Finally, the demand to put these laws into action extends far beyond the king's personal religious observance. It requires him to actively use his royal authority to correct injustices [אבן עזרא] and to firmly establish the Torah among all the Israelites [העמק דבר].
