Kabbalah su Esodo 19:5

Since the divine will desires them, and their will and “clinging” are directed toward Him, these [sefirot] constitute the first level of holiness for [Israel]. Afterwards in this manner [Israel] rises to [the level of] Tiferet, for such is the way from the perspective of His having chosen them. They cling to the Shekhinah, which chooses [them] for its needs and in order to unite herself with her husband, as [Scripture] states, You shall be My own treasure (Exod. 19:5). Afterwards, as they cling to her, they are [also] clinging to Tiferet, as [Scripture] states, You who cleaved to the Lord your God (Deut. 4:4), referring to Tiferet and ‘Ateret.¹⁰‘Ateret is closely connected with Tiferet in the following verses: Isa. 62:3, Jer. 13:18, Prov. 4:9 and 16:31.
