"Lay violent hands on" means to touch or grasp someone with the intention of using physical force or violence against them. It implies an assault or the imminent threat of an assault.
In essence, the phrase suggests:
- Physical Contact: Direct touching or grabbing of another person.
- Violence or Threat of Violence: The act is not merely contact but one charged with aggression and the potential for harm.
- Intent: A conscious decision to use physical force against the person.
The idiom "lay hands on" by itself can have different meanings, including to find something or to gently touch, often in a healing or blessing context. However, when modified with "violent," it unequivocally refers to a hostile and forceful action.
