Exodus 19:1-6 CJB

1 In the third month after the people of Isra'el had left the land of Egypt, the same day they came to the Sinai Desert.
2 After setting out from Refidim and arriving at the Sinai Desert, they set up camp in the desert; there in front of the mountain, Isra'el set up camp.
3 Moshe went up to God, and ADONAI called to him from the mountain: "Here is what you are to say to the household of Ya'akov, to tell the people of Isra'el:
4 'You have seen what I did to the Egyptians, and how I carried you on eagles' wings and brought you to myself.
5 Now if you will pay careful attention to what I say and keep my covenant, then you will be my own treasure from among all the peoples, for all the earth is mine;
6 and you will be a kingdom of cohanim for me, a nation set apart.'These are the words you are to speak to the people of Isra'el."
