Esodo 37:1 Commento: Rashi, Da'at Zekenim, Rabbeinu Bahya & Siftei Chakhamim

ויעש בצלאל AND BEZALEL MADE [THE ARK] — Because he gave himself over to the work more whole-heartedly than the other wise men it is called after his name (his name alone is associated with the act) (Midrash Tanchuma, Vayakhel 10).

ויעש בצלאל את הארון, “Betzalel constructed the Ark.” It was the first of the furnishings of the Tabernacle. This corresponds to what we read in Psalms 119,130: and פתח דבריך יאיר מבין פתיים, “even the preamble to the words You inscribed give light.” David referred to the “light” G–d had created on the first day prior to proceeding to creating the three dimensional universe. This is what the Holy Ark represented in the Tabernacle as the Torah it contained has been defined by Solomon in Proverbs 6,23 as: כי נר מצוה ותורה אור, “for the individual commandment is a lamp, whereas the Torah as a whole represents light itself.” The reason why you do not find Betzalel’s name associated with any of the furnishings of the Tabernacle other than the Holy Ark, is that in connection with that item Betzalel had demonstrated the degree of holy spirit which G–d had endowed him with. Moses had suggested to Betzalel to construct the Holy Ark as the first item to be made for the Tabernacle, whereupon Betzalel upon hearing this questioned it by saying to him: “are you sure? Does one not build a house before making the furniture for it?” Moses then remembered that he had forgotten the order in which G–d had told him to proceed. Our sages kept this story alive by pointing out that the meaning of Betzalel’s name בצל-אל is: ”in the shadow of G–d,” i.e. he must have been nearby when G–d instructed Moses. (Compare Talmud, tractate B’rachot folio 55)

ויעש בצלאל את הארון, “Betzalel constructed the Ark.” It is well known that the Ark was the most sacred of all the furnishings of the Tabernacle. This is the reason why the Torah mentions Betzalel’s name in connection with the construction of the Ark, seeing that he was the one who possessed most of this divine spirit with which G’d endowed all the participants in the work of constructing the Tabernacle. (Compare the adjectives the Torah lavished on his insights in 35,31).
Furthermore, the construction of the Ark required that the person making it entertained specific thoughts while making it. Seeing that construction of the other furnishings did not demand that the craftsman engaged in making it entertained specific thoughts, the Torah contented itself with simply writing: “he made it,” (the table) or (the lampstand), etc. without mentioning who it was who made it.”
