Exodus 19:1-6

1 Exactly two months after the Israelites left Egypt, they arrived in the wilderness of Sinai.
2 After breaking camp at Rephidim, they came to the wilderness of Sinai and set up camp there at the base of Mount Sinai.
3 Then Moses climbed the mountain to appear before God. The LORD called to him from the mountain and said, “Give these instructions to the family of Jacob; announce it to the descendants of Israel:
4 ‘You have seen what I did to the Egyptians. You know how I carried you on eagles’ wings and brought you to myself.
5 Now if you will obey me and keep my covenant, you will be my own special treasure from among all the peoples on earth; for all the earth belongs to me.
6 And you will be my kingdom of priests, my holy nation.’ This is the message you must give to the people of Israel.”
