Exodus 19:7-9

So Moses called for the elders of the people, and told them all these words which the LORD commanded him. All the people answered together and said, “We will do everything that the LORD has spoken.” And Moses reported the words of the people to the LORD. The LORD said to Moses, “Behold, I will come to you in a thick cloud, so that the people may hear when I speak with you and may believe and trust in you forever.” Then Moses repeated the words of the people to the LORD.
