פירוש על ברכות 15:17

Gemara: "What does [the verse mean] when it writes: "Hashem loves the gates of Tzion more than all the dwellings of Yaakov?" [It means that] Hashem loves the gates that are distinguished (language of "metzuyanim" is similar to the word of Tzion in the verse quoted) in halacha more than the synagogues and the houses of study. And this [idea that the study of halacha is optimal is what was meant when] Rebbi Chiya bar Ami in the name of Ulla said: "From the day that the Beit HaMikdash was destroyed, HaKadosh Barchu is only [revealed] in this world exclusively in the four amot of halacha."
