hod shebbe hod: splendor within splendor
Otherwise rendered as humility within humility
What is the essence of humility? At the depths of our humility, the soul is encompassed by splendor. Because hod is sometimes rendered as humility, and other times as splendor, there must be a connection between these two aspects of the middah (character trait). One explanation, in a nutshell, is that by humbling ourselves, we are able to reflect the splendor of G-d.
In the eyes of others, those who are sincerely humble, are often overlooked; yet, their splendor radiates in unseen realms. On the other hand, those who aggrandize themselves, do so to be seen; yet, they may only be great in their own eyes. The splendor that lasts is conferred by G-d, and G-d alone. His glory outshines ours; yet, He may bestow some of His glory upon us, when we humble ourselves before Him.
“For thus saith the High and Lofty One that inhabiteth eternity, whose name is Holy: I dwell in the high and holy place, with him also that is of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite ones.” – Isaiah 59:7, JPS Tanach
