Exodus 19:7-9
Exodus 19:7-9 ASV
And Moses came and called for the elders of the people, and set before them all these words which Jehovah commanded him. And all the people answered together, and said, All that Jehovah hath spoken we will do. And Moses reported the words of the people unto Jehovah. And Jehovah said unto Moses, Lo, I come unto thee in a thick cloud, that the people may hear when I speak with thee, and may also believe thee for ever. And Moses told the words of the people unto Jehovah.
