Vort on Parshas Terumah
אמתים וחצי ארכו. ואמה וחצי רחבו (תרומה כה:י)
And the measurements were two and a half and one and a half.
Reb Shalom Rokeach of Belz zt’’l explains why the measurements were half measurements – anyone who wants to attain the true lights of the Torah and accept its yoke has to know that to obtain the yoke of the Torah, one has to have a broken heart.
