In the fourth aliyah the Torah returns to the subject of the Jewish people approaching Mt. Sinai. The Torah says they arrived there in the third month after leaving Egypt on the "same day". Rashi says the term "same day" is used to indicate that the Torah should be considered by each of us as new as if it were given today.
Moshe goes up the mountain alone to talk to G-d. G-d tells Moshe to "tell the Jews that they've seen what I did to the Egyptians and how I bore you on eagle's wings. If you will keep My covenant you will be My treasured people and a kingdom of priests."
