Exodus 19:17 YLT

¹⁵  and he saith unto the people, 'Be ye prepared for the third day, come not nigh unto a woman.'

¹⁶  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  And Moses bringeth out the people to meet God from the camp, and they station themselves at the lower part of the mount,

¹⁸  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  and the sound of the trumpet is going on, and very strong; Moses speaketh, and God doth answer him with a voice.
