Exodus 19
12 Ref And let limits be marked out for the people round the mountain, and say to them, Take care not to go up the mountain or near the sides of it: whoever puts his foot on the mountain will certainly come to his death:
13 Ref He is not to be touched by a hand, but is to be stoned or have an arrow put through him; man or beast, he is to be put to death: at the long sounding of a horn they may come up to the mountain.
14 Ref Then Moses went down from the mountain to the people, and made the people holy; and their clothing was washed.
15 Ref And he said to the people, Be ready by the third day: do not come near a woman.
16 Ref And when morning came on the third day, there were thunders and flames and a thick cloud on the mountain, and a horn sounding very loud; and all the people in the tents were shaking with fear.
17 Ref And Moses made the people come out of their tents and take their places before God; and they came to the foot of the mountain,
18 Ref And all the mountain of Sinai was smoking, for the Lord had come down on it in fire: and the smoke of it went up like the smoke of a great burning; and all the mountain was shaking.
19 Ref And when the sound of the horn became louder and louder, Moses' words were answered by the voice of God.
20 Ref Then the Lord came down on to Mount Sinai, to the top of the mountain, and the Lord sent for Moses to come up to the top of the mountain, and Moses went up.
21 Ref And the Lord said to Moses, Go down and give the people orders to keep back, for fear that a great number of them, forcing their way through to see the Lord, may come to destruction.
22 Ref And let the priests who come near to the Lord make themselves holy, for fear that the Lord may come on them suddenly.
