Mizmor 91

“He shall dwell in the shadow of the Almighty"

Berachos 55a: The architect and builder of the Tabernacle was בצלאל Bezalel whose name implies “in the shadow of G-d. Betzalel anticipated aspects of the Divine blueprint before Moshe revealed them. So amazed was Moshe that he asked, “Perhaps you reside in the shadow of G-d?”

Medrash Tanchuma (Naso 23): Moshe composed this Mizmor when he ascended Har Sinai. Moshe dwelt there in the secret refuge of the Most High for three periods of forty days, total of 120 days. The Hebrew word צל shadow, totals 120.

This Mizmor uses the word Shakai for the Divine Name, which alludes that the Almighty, although infinite, confined Himself into a finite world. Talmud (Chagigah 12a) explains that at creation, the world continued to grow until G-d said די enough.” Thus, only people like Moshe and Bezalel can dwell with G-d in the hiddenness of the world and still recognize Him as the Most High.
