In ancient Israel, the king was expected to be more than a political leader; he was to be a spiritual guide as well. By writing a personal copy of the law, the king would gain a deeper understanding and appreciation of God's commandments. This process was meant to instill humility and a sense of responsibility, reminding the king that his authority was derived from God and that he was subject to divine law. The involvement of the Levitical priests in providing the law ensured its accuracy and authenticity, reinforcing the sacred nature of this task.
This practice was designed to prevent the king from becoming arrogant or self-serving, as it constantly reminded him of his duty to lead with justice and righteousness. It emphasized that the king's power was not absolute but was to be exercised in accordance with God's will. This principle of accountability and adherence to divine law is a timeless lesson for leaders today, encouraging them to seek wisdom and guidance from higher principles in their decision-making processes.
