Hebrews 12:18-21

For you have not come [as did the Israelites in the wilderness] to a mountain that can be touched and to a blazing fire, and to gloom and darkness and a raging windstorm, and to the blast of a trumpet and a sound of words [such that] those who heard it begged that nothing more be said to them. [Ex 19:12-22; 20:18-21; Deut 4:11, 12; 5:22-27] For they could not bear the command, “IF EVEN A WILD ANIMAL TOUCHES THE MOUNTAIN, IT WILL BE STONED [to death].” [Ex 19:12, 13] In fact, so terrifying was the sight, that Moses said, “I AM FILLED WITH FEAR and trembling.” [Deut 9:19]
