In memory of Rabbi Levi Yitzchok ben R' Zalman Yuda Deitsch OBM
The prophet (Zechariah 9:9) states Moshiach will be "A poor man, riding on a donkey." In Hebrew, the word "chamor" - "donkey," is related to "chumriyut," meaning "materiality." Three "famous" donkeys mentioned in the Bible - the donkey of Abraham, of Moses, and of Moshiach - allude to three successive stages in the subordination and refinement of the materiality of the body and the materiality of the world. The light of Moshiach will be revealed through the very chamor/chumriyut itself: materiality will become so refined that it in itself will reveal the light of holiness in the world.
