Commentary for Exodus 35:34

ואהליאב AND OHOLIAB — he was of the tribe of Dan, of one of the lowest of the tribes, of the sons of the handmaids, and yet the Omnipresent placed him with regard to the work of the Tabernacle on a level with Bezalel although he was a member of one of the noble tribes (Judah)! in order to confirm what Scripture says, (Job 34:19) “He regardeth not the rich more than the poor” (Midrash Tanchuma 2:10:13).

ולהורות נתן בלבו, and He equipped his heart with the ability to teach, etc. There are many great scholars whose wisdom is locked up in their hearts due to their inability to transmit it successfully to outsiders. The ability to teach is a great gift, and this is why the Torah testifies that G'd granted this gift to Betzalel. There is also a moral lesson contained in this verse not to act like certain members of the family of Bet Gormu who wanted to preserve their monoply on the intricacies of preparing the show breads by not teaching their craft to any non-family member. The Talmud severely critised their behaviour (Yuma 38). People who do teach their crafts qualify for the blessing expressed by Solomon in Proverbs 10,7: "The memory of a righteous person is a source of blessing."

ולהורותם, and to teach others.

ולהורות, “and to give instruction,” (to others.)
