Exodus 19:7-9

Darby Translation

⁷ And Moses came and called the elders of the people, and laid before the mall these words which Jehovah had commanded him.

⁸ And all the people answered together, and said, All that Jehovah has spoken will we do! And Moses brought the words of the people back to Jehovah.

⁹ And Jehovah said to Moses, Lo, I will come to thee in the cloud's thick darkness, that the people may hear when I speak with thee, and believe thee also for ever. And Moses told the words of the people to Jehovah.
