A swearing-in ceremony is a formal event where individuals take an oath to assume a specific role or position, often in government or public service. This ceremony typically involves the person being sworn in promising to uphold the laws and responsibilities of their new role, such as a president, governor, or judge. During the ceremony, the individual usually places their hand on a Bible or another significant book while reciting the oath. Family, friends, and colleagues often attend to witness this important milestone, marking the beginning of the individual's official duties and responsibilities.
