Exodus 19:1-9

1In the third month, when the children of Israel had gone forth from the land of Egypt, the same day they came into the wilderness of Sinai. 2For they had departed from Rephidim, and had come to the desert of Sinai, and had pitched in the wilderness; and there Israel encamped before the mount. 3And Moses went up to God, and the LORD called to him from the mountain, saying, Thus shalt thou say to the house of Jacob, and tell the children of Israel; 4Ye have seen what I did to the Egyptians, and how I bore you on eagles’ wings, and brought you to myself. 5Now therefore, if ye will obey my voice indeed, and keep my covenant, then ye shall be a special treasure to me above all people: for all the earth is mine: 6And ye shall be to me a kingdom of priests, and an holy nation. These are the words which thou shalt speak to the children of Israel. 7And Moses came and called for the elders of the people, and laid before their faces all these words which the LORD commanded him. 8And all the people answered together, and said, All that the LORD hath spoken we will do. And Moses returned the words of the people to the LORD.

9And the LORD said to Moses, Lo, I come to thee in a thick cloud, that the people may hear when I speak with thee, and believe thee for ever. And Moses told the words of the people to the LORD.
