Exodus 19:3-7

Then Moses went up to God; the LORD called to him from the mountain, saying, “Thus you shall say to the house of Jacob, and tell the Israelites: 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 obey my voice and keep my covenant, you shall be my treasured possession out of all the peoples. Indeed, the whole earth is mine, but you shall be for me a priestly kingdom and a holy nation. These are the words that you shall speak to the Israelites.” So Moses came, summoned the elders of the people, and set before them all these words that the LORD had commanded him.
