Following the approach pioneered by Rav Mordechai Breuer, I would like two examine "shtei bechinot" (roughly meaning two aspects) in the Torah's description of God's descent on Mount Sinai (Shemot 19). If we examine the verses carefully, we will see that there are actually two accounts of this event, each containing different instructions to the Jewish People.

The first account appears in verses 10-19 (the actual descent is described in verse 18); the second account is in verses 20-25 (the actual descent is described in verse 20). (It would help at this point to have a Tanakh open in front of you.) In the following shiur, I will try to distinguish between the two descriptions and their meanings, and then to try to explain the connection between the two descriptions.
