Heavenly Joy

In this pasuk, the Torah uses the word “ma'on kadshecha” (Your holy abode), whereas Shlomo Hamelech (1 Malachim 8:39) “machon”, rather than “ma'on", Rabenu Bechaya explains that when one brings bikkurim, he testifies to the joy he feels upon fulfilling the commandments, and says: "And You shall hear in Heaven Your dwelling place..." and this joy is felt in the Heavenly realm known as “ma'on", which is why this word is used in the vidui.
