Hebrews 12:18-21

18For you have not come to what may be touched, a blazing fire and darkness and gloom and a tempest 19and the sound of a trumpet and a voice whose words made the hearers beg that no further messages be spoken to them. 20For they could not endure the order that was given, “If even a beast touches the mountain, it shall be stoned.” 21Indeed, so terrifying was the sight that Moses said, “I tremble with fear.”
