אמר ריש לקיש פעמים
Reish Lakish says: Sometimes
שביטולה של תורה זהו יסודה דכתיב (שמות לד, א) אשר שברת אמר לו הקב"ה למשה יישר כחך ששברת
the apparent dereliction of the study of Torah is its foundation, e.g., if one breaks off his studies in order to participate in a funeral or a wedding procession. This is derived from a verse, as it is written: “And the Lord said to Moses: Hew for yourself two tablets of stone like the first, and I will write upon the tablets the words that were on the first tablets, which [asher] you broke” (Exodus 34:1). The word “asher” is an allusion to the fact that that the Holy One, Blessed be He, said to Moses: Your strength is true [yishar koḥakha] in that you broke the tablets, as the breaking of the first tablets led to the foundation of the Torah through the giving of the second tablets.
