And the ability to instruct he instilled in his heart: And its Targum (Targum Yonatan on Exodus 35:34) is, "and to teach the crafts." And on, "And to design designs" (Exodus 35:32), the Targum is also, "And to teach the crafts." And to explain this, we need to preface [the Sages'] statement, may their memory be blessed, (Berakhot 55a:13), "Bezalel knew how to combine the letters with which the heavens and the earth were created." And there is a need to understand what requirement there is for him to know this, in order to build the tabernacle. However the matter is like this: It is known that the Holy One, blessed be He, looked into the Torah and created the world, and the verse assists [this understanding], "I was with Him as a confidant (oman)" (Proverbs 8:30) - do not read [it as], "confidant," but rather [as], "craftsman (uman)." See there (Zohar, Trumah 61:635). And it is known that the tabernacle was also a model of the design of the entire creation of the heavens and the earth. For everything was included in it in order to connect the higher beings and the lower beings, as it is found in the commentators. And in the Midrash: Everything that was stated in the act of creation was stated with the tabernacle. Such as, "And God completed (vayekhal), on the seventh day, His work that He had done" (Genesis 2:20); and it is also stated (Exodus 40:33), "and Moshe completed (vayekhal) the tabernacle, etc." See there. It comes out that for the building of the tabernacle, it is required to know how to combine the letters through which the heavens and the earth were created. And this is [the meaning of] that which the Sages, may their memory be blessed, said, "Betzalel knew, etc." And those were the letters of the Torah, through which the world was built. And it can be said that this is what it hints over here - "And the ability to instruct he instilled in his heart." Backwards, that is, in the heart he instilled Torah (instruction). And that is that which [the Targum Yonatan] translated, "and to teach the crafts." Meaning, that he would teach and study the Torah, which is the craft of the Holy One, blessed be He, with the combination of the letters through which the heavens and the earth were created. And through this, he was also able to design designs for the service and the crafts for the tabernacle. For it is all with one secret. So does it appear to me.
