Exodus 19:3-7 New Revised Standard Version (NRSV)
3 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: 4 You have seen what I did to the Egyptians, and how I bore you on eagles’ wings and brought you to myself. 5 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, 6 but you shall be for me a priestly kingdom and a holy nation. These are the words that you shall speak to the Israelites.”
7 So Moses came, summoned the elders of the people, and set before them all these words that the Lord had commanded him.
