20 Then God began to speak directly to all the people.
Until now God has dealt only with Moses on behalf of His people; at Mount Sinai, He turns to address them directly in order to express the core of His covenant obligations. He begins by reminding them of all He has done for them. His miraculous deeds in liberating the Hebrew slaves and providing for them in the desert become the basis of this new relationship. He then proceeds to lay out the Ten Directives that will define and shape their lives together. The first four Directives concern their duties to know and worship the one True God. The last six pertain to how Israel is to live with one another in a covenant-based society. Properly understood, all the other teachings, prescriptions, and directives that come in later chapters derive from these Ten Directives.
Eternal One: 2 I am the Eternal your God. I led you out of Egypt and liberated you from lives of slavery and oppression.
3 You are not to serve any other gods before Me.
