Exodus 19
16 Ref And it cometh to pass, on the third day, while it is morning, that there are voices, and lightnings, and a heavy cloud, on the mount, and the sound of a trumpet very strong; and all the people who `are' in the camp do tremble.
17 Ref And Moses bringeth out the people to meet God from the camp, and they station themselves at the lower part of the mount,
18 Ref and mount Sinai `is' wholly a smoke from the presence of Jehovah, who hath come down on it in fire, and its smoke goeth up as smoke of the furnace, and the whole mount trembleth exceedingly;
19 Ref and the sound of the trumpet is going on, and very strong; Moses speaketh, and God doth answer him with a voice.
