She is greatly admired for her breadth of knowledge in matters pertaining to both halachah and aggadah, and is said to have learned from the rabbis 300 halachot on a single cloudy day.
The Gemara relates an additional example of Berurya’s incisive insight: A certain heretic said to Berurya: "It is written: 'Sing, barren woman who has not given birth, open forth in song and cry, you did not travail, for more are the children of the desolate than the children of the married wife, said the Lord (Isaiah 54:1).' Because she has not given birth, she should sing and rejoice?"
Berurya responded to this heretic’s mockery and said: "Fool! Go to the end of the verse, where it is written: 'For the children of the desolate shall be more numerous than the children of the married wife, said the Lord.' Rather, what is the meaning of: 'Sing, barren woman who has not given birth'? It means: Sing congregation of Israel, which is like a barren woman who did not give birth to children who are destined for Gehenna like you."
רַבִּי יוֹסֵי הַגְּלִילִי הֲוָה קָא אָזֵיל בְּאוֹרְחָא, אַשְׁכְּחַהּ לִבְרוּרְיָה אֲמַר לַהּ: בְּאֵיזוֹ דֶּרֶךְ נֵלֵךְ לְלוֹד? אֲמַרָה לֵיהּ: גָּלִילִי שׁוֹטֶה, לֹא כָּךְ אָמְרוּ חֲכָמִים: אַל תַּרְבֶּה שִׂיחָה עִם הָאִשָּׁה?! הָיָה לְךָ לוֹמַר: ״בְּאֵיזֶה לְלוֹד״.
Rabbi Yosei HaGelili was walking along the way, and met Berurya. He said to her: On which path shall we walk in order to get to Lod? She said to him: Foolish Galilean, didn’t the Sages say: Do not talk much with women? You should have said your question more succinctly: Which way to Lod?
בְּרוּרְיָה אַשְׁכַּחְתֵּיהּ לְהַהוּא תַּלְמִידָא דַּהֲוָה קָא גָרֵיס בִּלְחִישָׁה. בְּטַשָׁה בֵּיהּ, אֲמַרָה לֵיהּ: לֹא כָּךְ כָּתוּב ״עֲרוּכָה בַכֹּל וּשְׁמוּרָה״, אִם עֲרוּכָה בִּרְמַ״ח אֵבָרִים שֶׁלְּךָ — מִשְׁתַּמֶּרֶת, וְאִם לָאו — אֵינָהּ מִשְׁתַּמֶּרֶת. תָּנָא: תַּלְמִיד אֶחָד הָיָה לְרַבִּי אֱלִיעֶזֶר שֶׁהָיָה שׁוֹנֶה בְּלַחַשׁ, לְאַחַר שָׁלֹשׁ שָׁנִים שָׁכַח תַּלְמוּדוֹ.
The Gemara relates more of Berurya’s wisdom: Berurya came across a certain student who was whispering his studies rather than raising his voice. She kicked him and said to him: Isn’t it written as follows: “Ordered in all things and secure” (2 Samuel 23:5), which indicates that if the Torah is ordered in your 248 limbs, i.e., if you exert your entire body in studying it, it will be secure, and if not, it will not be secure. The Gemara relates that it was similarly taught in a baraita: Rabbi Eliezer had a student who would study quietly, and after three years he forgot his studies.
