The Talmud states that Betzalel knew how to combine the letters with which heaven and earth were created, and that chokhmah is the flash of insight while binah is the ability to derive and understand things from that initial insight (mevin davar mitokh davar).
אָמַר רַב יְהוּדָה אָמַר רַב: יוֹדֵעַ הָיָה בְּצַלְאֵל לְצָרֵף אוֹתִיּוֹת שֶׁנִּבְרְאוּ בָּהֶן שָׁמַיִם וָאָרֶץ. כְּתִיב הָכָא: ״וַיְמַלֵּא אֹתוֹ רוּחַ אֱלֹהִים בְּחׇכְמָה וּבִתְבוּנָה וּבְדַעַת״, וּכְתִיב הָתָם: ״ה׳ בְּחׇכְמָה יָסַד אָרֶץ כּוֹנֵן שָׁמַיִם בִּתְבוּנָה״. וּכְתִיב: ״בְּדַעְתּוֹ תְּהוֹמוֹת נִבְקָעוּ״. אָמַר רַבִּי יוֹחָנָן: אֵין הַקָּדוֹשׁ בָּרוּךְ הוּא נוֹתֵן חָכְמָה אֶלָּא לְמִי שֶׁיֵּשׁ בּוֹ חָכְמָה, שֶׁנֶּאֱמַר: ״יָהֵב חׇכְמְתָא לְחַכִּימִין וּמַנְדְּעָא לְיָדְעֵי בִינָה״. שְׁמַע רַב תַּחְלִיפָא בַּר מַעְרְבָא וְאַמְרַהּ קַמֵּיהּ דְּרַבִּי אֲבָהוּ. אָמַר לֵיהּ: אַתּוּן מֵהָתָם מַתְנִיתוּ לַהּ, אֲנַן מֵהָכָא מַתְנִינַן לַהּ, דִּכְתִיב: ״וּבְלֵב כׇּל חֲכַם לֵב נָתַתִּי חׇכְמָה״.
Rav Yehuda said that Rav said: Bezalel knew how to join the letters with which heaven and earth were created. From where do we derive this? It is written here in praise of Bezalel: “And I have filled him with the spirit of God, in wisdom, and in understanding, and in knowledge, and in all manner of workmanship” (Exodus 31:3); and it is written there with regard to creation of heaven and earth: “The Lord, by wisdom, founded the earth; by understanding He established the heavens” (Proverbs 3:19), and it is written: “By His knowledge the depths were broken up and the skies drop down the dew” (Proverbs 3:20). We see that wisdom, understanding, and knowledge, the qualities with which the heavens and earth were created, are all found in Bezalel. On a similar note, Rabbi Yoḥanan said: The Holy One, Blessed be He, only grants wisdom to one who already possesses wisdom, as it is stated: “He gives wisdom unto the wise, and knowledge to they who know understanding” (Daniel 2:21). Rav Taḥalifa, from the West, Eretz Yisrael, heard this and repeated it before Rabbi Abbahu. Rabbi Abbahu said to him: You learned proof for this idea from there; we learn it from here: As it is written in praise of the builders of the Tabernacle: “And in the hearts of all who are wise-hearted I have placed wisdom” (Exodus 31:6).
