Exodus 19:4-6 Contemporary English Version (CEV)
4 You saw what I did in Egypt, and you know how I brought you here to me, just as a mighty eagle carries its young. 5 Now if you will faithfully obey me, you will be my very own people. The whole world is mine, 6 but you will be my holy nation and serve me as priests.
Moses, that is what you must tell the Israelites.
