Exactly three months after the Israelites had left Egypt, they reached the Desert of Sinai.
When they left Rephidim, they came to the Desert of Sinai and camped in the desert in front of the mountain.
Then Moses went up on the mountain to God. The Lord called to him from the mountain and said, "Say this to the family of Jacob, and tell the people of Israel:
'Every one of you has seen what I did to the people of Egypt. You saw how I carried you out of Egypt, as if on eagle's wings. And I brought you here to me.
So now if you obey me and keep my agreement, you will be my own possession, chosen from all nations. Even though the whole earth is mine,
you will be my kingdom of priests and a holy nation.' You must tell the Israelites these words."
