Exodus 19:4-6

4‘You have seen for yourselves what I did to Egypt, and how I carried you on eagles’ wings and brought you to Myself. 5Now if you will indeed obey My voice and keep My covenant, you will be My treasured possession out of all the nations—for the whole earth is Mine. 6And unto Me you shall be a kingdom of priests and a holy nation.’ These are the words that you are to speak to the Israelites.”
