Exodus 19:1-7

In the third month after the children of Israel had gone out of the land of Egypt, on the same day, they came to the Wilderness of Sinai. For they had departed from Rephidim, had come to the Wilderness of Sinai, and camped in the wilderness. So Israel camped there before the mountain. And Moses went up to God, and the LORD called to him from the mountain, saying, “Thus you shall say to the house of Jacob, and tell the children of Israel: ‘You have seen what I did to the Egyptians, and how I bore you on eagles’ wings and brought you to Myself. Now therefore, if you will indeed obey My voice and keep My covenant, then you shall be a special treasure to Me above all people; for all the earth is Mine. And you shall be to Me a kingdom of priests and a holy nation.’ These are the words which you shall speak to the children of Israel.” So Moses came and called for the elders of the people, and laid before them all these words which the LORD commanded him.
