RE: Proverbs 3:27
YES, there are many laws that require you, under certain circumstances to render aid.
2010 Pennsylvania Code, Title 75 - VEHICLES, Chapter 37 - Miscellaneous Provisions, 3744 - Duty to give information and render aid.
§ 3744. Duty to give information and render aid.
(a) General rule.--The driver of any vehicle involved in an accident resulting in injury to or death of any person or damageto any vehicle or other property which is driven or attended by any person shall give his name, address and the registration number of the vehicle he is driving, and shall upon request exhibit his driver's license and information relating to financial responsibility to any person injured in the accident or to the driver or occupant of or person attending any vehicle or other property damaged in the accident and shall give the information and upon request exhibit the license and information relating to financial responsibility to any police officer at the scene of the accident or who is investigating the accident and shall render to any person injured in the accident reasonable assistance, including the making of arrangements for the carrying of the injured person to a physician, surgeon or hospital for medical or surgical treatment if it is apparent that treatment is necessary or if requested by the injured person.
Note the phrase I have flagged: "shall render to any person injured in the accident reasonable assistance"
