קדושה – Holiness (sanctity, divinity)
The Kedusha is part of the Amida prayer, where we stand with straight legs like angels and recite the words “קדוש קדוש קדוש” “Holy Holy Holy” (Pronounced “Kadosh Kadosh Kadosh”)
Myriad number of angels at all levels wait for Israel below to say the Kedusha so they can join them because they cannot say it until Israel do that.
The Kedusha comes from these two verses;
“וְקָרָא זֶה אֶל זֶה וְאָמַר קָדוֹשׁ קָדוֹשׁ קָדוֹשׁ יְהוָה צְבָאוֹת מְלֹא כָל הָאָרֶץ כְּבוֹדוֹ.”
“And one cried to another and said: “Holy, holy, holy is the LORD of hosts; The whole earth is full of His glory!”
“וַתִּשָּׂאֵנִי רוּחַ וָאֶשְׁמַע אַחֲרַי קוֹל רַעַשׁ גָּדוֹל בָּרוּךְ כְּבוֹד־יְהֹוָה מִמְּקוֹמוֹ”
“Then the Spirit lifted me up, and I heard behind me a great thunderous voice: “Blessed is the glory of the LORD from His place!”
