내가 또 단 지파 아히사막의 아들 오홀리압을 세워 그와 함께 하게 하며 무릇 지혜로운 마음이 있는 자에게 내가 지혜를 주어 그들로 내가 네게 명한 것을 다 만들게 할지니
Rashi
ובלב כל חכם לב וגו׳ AND IN THE HEARTS OF ALL THAT ARE WISE HEARTED [I HAVE GIVEN WISDOM] — and there are still other wise-hearted men among you (beside Bezalel and Oholiab) and all these in whom I have given wisdom shall make all that I have commanded thee.
Rashbam
ובלב כל חכם לב, who came forward to carry out this work G’d had already equipped him with the required talent to carry out the work.
Rabbeinu Bahya
ואני הנני נתתי אתו את אהליאב בן אחיתמך למטה דן, “As for Me, here I have given him as an assistant Oholiav son of Achisamach of the tribe of Dan.” We read in the name of Rabbi Chanina in Shemot Rabbah 40,4 that no tribe was more exalted than Yehudah and none was less regarded than the tribe of Dan, seeing he was descended from one of the maidservants of Yaakov. G’d decided that Betzalel and a descendant of Dan should partner each other so that neither Betzalel nor his tribe should become haughty. All human beings are equal before G’d. The fact that the Tabernacle was built by these two architects was an important object lesson teaching this parity between the tribes in their social standing. Interestingly enough, when Solomon built the Temple this pattern was repeated seeing that the principal participants in constructing it were Solomon of the tribe of Yehudah, and Chirom the son of a mother from the tribe of Dan (compare Chronicles II 2,13).
