the son of a woman of the daughters of Dan, and his father was a man of Tyre, skilful to work in gold, and in silver, in brass, in iron, in stone, and in timber, in purple, in blue, and in fine linen, and in crimson; also to grave any manner of graving, and to devise any device; to do whatever may be set before him, with thy skilful men, and with the skilful men of my lord David thy father.
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).
