Don’t we just want to leave Mitzrayim, our: בֵית עֲבָּדִּ ים place of slavery? Why is having a Yom Tov part of leaving? Because a Chag is fun and Geshmak and relaxed. This is what Avodas Hashem really is, like it says: אֵין לְךָ בֶן חוֹרִּ ין אֶלָּא מִּי שֶעוֹסֵק בְתוֹרָּה אבות ו ג the “true” free man is the person who learns (and follows) the Torah, which is: מְשַמְחֵי לֵב תהלים יט ט (brings joy to your heart). We also left the country that never has rain, and never connects to Shamayim. They never look up. Perhaps this is why in the Midbar we had the Mon, which is Lechem Min HaShamayim.
Also, it is interesting that the meek sheep was actually a god in Mitzrayim, and a sheep is a kosher and nonaggressive creature. And we had a Mitzva to Shecht their god in front of them. We can suggest that being meek and unable to do as you wish is the exact Yetzer Hara of Mitzrayim. A sheep has no mind of its own. It just follows.
This is a “Mitzri” who is in a “Meitzar”, boundary mode, since he’s trapped by his Yetzer Hara. And we Shecht our Yetzer Hara before their eyes, and we are called: צִּבְאוֹת ה' army men. Why when we leave Mitzrayim, are we suddenly army men? Who are we fighting? The Yetzer Hara! A strong soldier is the opposite of a docile sheep. A soldier is a symbol of power. And we left Mitzrayim: חֲמֻשִּ ים בשלח יג יח with arms!
