Upside Down: flipping, reversals and turning everything on its head
(א) וּבִשְׁנֵים֩ עָשָׂ֨ר חֹ֜דֶשׁ הוּא־חֹ֣דֶשׁ אֲדָ֗ר בִּשְׁלוֹשָׁ֨ה עָשָׂ֥ר יוֹם֙ בּ֔וֹ אֲשֶׁ֨ר הִגִּ֧יעַ דְּבַר־הַמֶּ֛לֶךְ וְדָת֖וֹ לְהֵעָשׂ֑וֹת בַּיּ֗וֹם אֲשֶׁ֨ר שִׂבְּר֜וּ אֹיְבֵ֤י הַיְּהוּדִים֙ לִשְׁל֣וֹט בָּהֶ֔ם וְנַהֲפ֣וֹךְ ה֔וּא אֲשֶׁ֨ר יִשְׁלְט֧וּ הַיְּהוּדִ֛ים הֵ֖מָּה בְּשֹׂנְאֵיהֶֽם׃

(1) And so, on the thirteenth day of the twelfth month—that is, the month of Adar—when the king’s command and decree were to be executed, the very day on which the enemies of the Jews had expected to get them in their power, the opposite happened, and the Jews got their enemies in their power.

(ו) נִטְמָא קָהָל אוֹ רֻבּוֹ, אוֹ שֶׁהָיוּ הַכֹּהֲנִים טְמֵאִים וְהַקָּהָל טְהוֹרִים, יֵעָשֶׂה בְטֻמְאָה.

(6) If the entire community or most of it became ritually impure, or the priests were all impure and the community was pure, they should perform the ritual of the Paschal lamb in ritual impurity (and not on on the second Pesaḥ.)

(כב) בֶּן בַּג בַּג אוֹמֵר, הֲפֹךְ בָּהּ וַהֲפֹךְ בָּהּ, דְּכֹלָּא בָהּ.

(22) Ben Bag Bag said: Turn it over, and [again] turn it over, for all is therein.

Personal Accounts from the Chassidic Master, the Esh Koshes (Rav Shapira):
I will turn flips like those lowly people who debase themselves in order to bring joy to their employer....For when I just began to think about doing the somersaults, my thoughts and soul burned with a sense of self-sacrifce...Why is it that my body trembled and was sanctified by it? It must be due to the sparks of goodness, that even the lowest [person] merits, which collected in me, and were now created. Thus I was very happy when I later discovered that KingDavid somersaulted in front of the Holy Ark

“Do not worry that your life is turning upside down. How do you know the side you are used to is better than the one to come?”
