And the LORD said unto Moses, Lo, I come unto you in a thick cloud, that the people may hear when I speak with you, and believe you forever. And Moses told the words of the people unto the LORD.
While he yet spoke, behold, a bright cloud overshadowed them: and behold a voice out of the cloud, which said, This is my beloved Son, in whom I am well pleased; hear you him.
And it came to pass on the third day in the morning, that there were thunders and lightnings, and a thick cloud upon the mount, and the voice of the trumpet exceedingly loud; so that all the people that were in the camp trembled.
And the glory of the LORD abode upon mount Sinai, and the cloud covered it six days: and the seventh day he called unto Moses out of the midst of the cloud.
