God doesn't feel anger like humans do; references to divine anger in Jewish texts are metaphors for people. Shabbat is the foundational covenant between God and Israel, a perpetual agreement linking creation's six days of work and one day of rest to Mount Sinai, articulated through the Kiddush prayer.
Chapters
The Torah talks to people in their own language. Make Hashem very angry. You really think that Hashem is fuming and is banging on the table? That's only between people. Hashem doesn't get fuming and doesn't get angry. He just speaks to us in a language that we can understand. If you break Shabbat, you get me very angry, very upset. And the Gemara say that Hashem is crying. I give you a chance to be like me. אני לא קראתי משהו בשבוע שבע, את אח שלי, אני שמעתי את עצמכם, את צריכה להיות כמו אני, אני לא קראתי בשבת, את לא תקראתי, את לא תקראתי, את לא תקראתי, את לא תקראתי, את לא תקראתי, את לא תקראתי, את לא תקראתי, את לא תקראתי, את לא תקראתי, את לא את לא תקראתי, את את You לא תקראתי, keep את לא the agreement תקראתי, that we made in Mount Sinai, את when you die I will pay you pleasure for eternity, לא you cannot תקר imagine, forever and ever. Shabbat is the foundation of all Judaism. Shabbat is the connection between Hashem, is the handshake between Hashem and us. What do we say in the Kiddush? ושאמרו בני ישראל את השבת. The nation of Israel observed the Sabbath. לעשות את השבת לדורותם ברית עולם. To make Shabbat an eternal covenant for generations. ביני ובני ישראל אותי לעולם. Between me and the nation of Israel it's a sign for eternity. That I created the world in six days and in the seventh day I rested.
