Exodus 19:7-9

American Standard Version

⁷ And Moses came and called for the elders of the people, and set before them all these words which Jehovah commanded him. ⁸ 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. ⁹ 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.
