The commandment you are referring to is most likely the concept of "Obedience" or "Submission" in a toxic or manipulative relationship. It is important to recognize that no healthy relationship should involve one partner being forced to adhere to the commands of the other. It is crucial to prioritize mutual respect, communication, and consent in any relationship. If you or someone you know is experiencing coercion or manipulation in a relationship, it is important to seek support from trusted friends, family, or professionals.
