Exodus 19:3-6 (New International Version)

 ³ Then Moses went up to God, and the LORD called to him from the mountain and said, "This is what you are to say to the house of Jacob and what you are to tell the people of Israel: ⁴ 'You yourselves have seen what I did to Egypt, and how I carried you on eagles' wings and brought you to myself. ⁵ Now if you obey me fully and keep my covenant, then out of all nations you will be my treasured possession. Although the whole earth is mine, ⁶ you ^[a] will be for me a kingdom of priests and a holy nation.' These are the words you are to speak to the Israelites."
