9 The Lord said to Moses, “I am going to come to you in a dense cloud, so that the people may hear when I speak with you and so that they will always believe in you.” And Moses told the words of the people to the Lord. 10 The Lord said to Moses, “Go to the people and sanctify them today and tomorrow, and make them wash their clothes 11 and be ready for the third day, for on the third day the Lord will come down on Mount Sinai in the sight of all the people. 12 You must set boundaries for the people all around, saying, ‘Take heed to yourselves not to go up on the mountain nor touch its edge. Whoever touches the mountain will surely be put to death! 13 No hand will touch him—but he will surely be stoned or shot through, whether a beast or a human being; he must not live.’ When the ram’s horn sounds a long blast they may go up on the mountain.”

2 He began his parable and said, Enoch, a righteous man, whose eyes were opened by God, saw the vision of the Holy One in the heavens, shown to him by the angels. He heard everything from them, and from them he understood what he saw, not for his own generation, but for a distant one yet to come. 3 Regarding the chosen, he spoke and taught about them: The Holy Great One will emerge from His dwelling, 4 And the eternal God will walk upon the earth, even on Mount Sinai, and appear from His camp and reveal His might from the heavens above. 5 Everyone will be struck with fear and the Watchers will tremble, and great fear and trembling will grip them to the ends of the earth. 6 The high mountains will shake, the hills will be leveled, and they will melt like wax before the fire
